M4 is not an assault rifle. It is a shortened carbine. It is suitable for close quarter combat.

Let us talk more about a military assault rifle which every soldier will carry.

A psychological impression has been created that everything is wrong with INSAS. That is not true. INSAS rifle won the Kargil war. Other than arms merchant and glossy brochure extolling virtues of their assault rifle, the Westerners are misleading the Indian Army. Some special multi calib rifles are needed for special purposes. Trial and procurement process for that is already on going.

Please do not scare an average soldier that everything is wrong with INSAS. When they start using the imported pricey stuff they will find out that something is wrong with each and every one of them. At that time you would be stuck with a pricey solution for a non existent problem.

Technically speaking, M4, M16, AK-74, INSAS, all are carbines, because they fire intermediate cartrige. However for example FN FAL or G3 are rifles because they fire rifle cartrige.

US MK12 developed after iraq/afhan war and its new ammo. PRI is the current company that manufacture both military and civilian of MK12. the upper is same for both military and civilian.
MK262 is new ammo for the US force, 77grain sierra match ammo produce exceptional accuracy out to 800meter, some shooter can hit out to 900-1000meter. however its still a 5.56 so its lethality at longer range is reduced significantly

Mark12 Mod 0 SPR
The Best 5.56 Load: The Black Hills MK 262 Mod 1 - Shooting Times

By Tom Beckstrand

Tactical Operator (shootingtimes.com)

Where Crane, the Creator of the MK 12, should have left well enough alone.

When the Global War on Terror (GWOT) started after 9/11, our nation's Special Operations Forces took to the field armed with M9 pistols, M4 carbines, M24 bolt-action sniper rifles and M249 and M240 machine guns.

Some units were carrying Knight's Armament SR-25s and Accuracy International AWM .338 Lapua Magnum sniper rifles. We had a handle on sniper rifles and machine guns, but we had one hell of an operational seam laying between our M4 carbine and the sniper rifles.

A seam occurs when there's a gap in one's capabilities, a place where we lack the appropriate tools to effectively engage the enemy. The M4 works well for general running-and-gunning duties out to about 200 meters. Generally equipped with a holographic or red dot sight, the M4 is a wise choice for every man on the team.

When we stretch the distance past 200 meters, our choices (at least in the fall of 2001) quickly became limited. We could either put a scope on an M4 and hope the approximately two-MOA rack- grade accuracy was up to the task, or we could grab and/or carry an additional sniper rifle for those times when we wanted to reach out and touch someone. Neither option is a great choice.

Our nation's Special Operations Forces quickly identified this seam in our capabilities and moved to correct the problem. The Naval Special Warfare Center, Crane Division, led the charge. Crane, with the input of our special operations soldiers, determined that an accurized 5.56mm platform was in order and that such a rifle could cover the seam in our capabilities.

THE SPR'S GREATEST STRENGTH

The greatest improvement that the SPR has over a traditional M4 is the barrel. The barrel is made by Douglas Barrels and is an 18-inch, button-rifled 1:7 twist with a rifle-length gas system. Douglas also only uses its premium barrels for the Mk 12. No barrel is ever perfectly straight, but the premium barrels on the Mk 12 are the straightest ones Douglas has and are probably much straighter than anything on a factory-produced rifle.

Douglas is well known in the custom- barrel-maker industry, and it's rare to see a true custom barrel used on an AR- pattern rifle. This is why we'll probably never see the Mk 12 mass-produced; the barrels are just too few in number to ever produce them in great quantity. Douglas ranks with Broughton, Pac-Nor and Shilen as the most distinguished button-rifled barrel makers in the industry. Broughton, Douglas and Shilen have all been around long enough to have multiple benchrest and F-class titles under their belts, a sure indicator of the barrel's potential.

The Douglas barrel on the SPR also has a rifle-length gas system. The long gas system offers a couple of substantial advantages over shorter- length systems. The first and greatest advantage is that it has substantially lower port pressure than carbine- or mid-length gas systems.

As a bullet passes down the bore, the pressure behind the projectile drops because the volume the gas has to fill is increasing. The closer the gas port is to the chamber of the barrel, the higher the pressure at the port will be. Pushing the gas port of the Mk 12 all the way down to a rifle-length system means it will have the lowest pressure possible for an AR-pattern rifle.

Port pressure matters because it determines how fast the bolt and bolt carrier cycle and operate. When we first started experimenting with carbine- length systems, we found that the extractor needed some modification to handle the increased cycling speed of the carbine system as a result of its much higher port pressure. The higher pressure made the bolt carrier and bolt move faster, and that increased speed caused the extractor to fail. Hence the birth of the SOPMOD kit that puts the little rubber donut around the extractor spring to give it the additional resilience against wear.

Fast bolt issues have largely been fixed with the carbine-length gas system, and they make for supremely reliable guns. However, I still think it's a good idea to shoot the longest gas system possible. A slow bolt is a happy bolt. It will last longer and give you fewer problems in the long run. The SPR has the longest-length gas system possible, to give the shooter the least maintenance-intensive firearm that will run for the longest amount of time.

SHOULD HAVE QUIT WHILE THEY WERE AHEAD

Crane did an excellent job with the SPR program when it created the SPR Mod 0 variant. This is the variant that we had on my first Special Forces team, and it was a popular rifle among my teammates. The Mod 0 variant I received for review features PRI's Gen III 121/2-inch free-float fore-end.

The PRI fore-end has plenty of length for positional shooting and still leaves enough space for the addition of sling swivel mounts, lasers and night-vision equipment. The SPR fore-end also has a continuous top rail that makes it possible to mount a scope in traditional rings forward enough to give the shooter proper eye relief. Made of carbon fiber, aluminum and steel, it is an excellent combination of light weight and strength.

The round shape of the fore-end is definitely the way to go for a rifle destined for combat use. Round fore- ends tend to be much slimmer than the traditional quad rail, even before we slap rail covers all over the quad rail to keep it from biting into the support hand when using a sling or carrying the rifle for extended periods of time. The PRI fore-end has comfort, light weight and strength; it's a winning combination for the Mod 0.

Then Crane screwed up with Mod 1. Sigh (I wish you could see me rolling my eyes as I write this). The big problem with the Mod 1 is the hand-guard. Crane went to the Knight's Armament Rail Adaptor System (RAS) and lost the continuous top rail that came with the Mod 0 (one of its many strengths) and the slim and comfortable round fore-end. The PRI fore-end was greatly superior.

I don't know why Crane went to the KAC fore-end, other than Crane must have some kind of special relationship with KAC. If you look at pictures of soldiers carrying the Mk 12 in combat, pay attention to how they mount their scopes on the Mod 0 versus the Mod 1. (You can find a lot of sweet action photos on mk12.net.)

Most of the scopes that soldiers mount on their rifles are in traditional scope rings because that's what they're issued. Scopes mounted on the Mod 0 take advantage of the continuous top rail and place the scope well forward of the seam that exists where the upper receiver and fore-end meet. The Mod 0 has a continuous top rail, so this is no problem. The continuous top rail will let a soldier do whatever he wants, optics-wise.

Now look at the pics of guys carrying the Mod 1. In those photos you'll see the forward ring mounted all the way forward on the upper receiver and the turrets of the scope mashed all the way forward into the back of that ring. This is because the traditional quad rail will not allow the proper eye relief without a cantilevered mount. A good cantilevered mount will run about $200. That's a lot of money to a soldier, so they make do with what they are issued and put up with the improper eye relief.

The Mk 12 Mod 0 represents the pinnacle of the SPR design as it was fielded. The great barrel, superb fore-end and continuous top rail all combine to make for an exceptionally user-friendly rifle.

The Mod 1 took a huge leap backward, but it still held on to the Douglas barrel and all of its goodness. While less than optimal, the Mod 1 is still relevant on today's battlefield.


AN SPR WAR STORY

When I was deployed to Afghanistan, my first exposure to the SPR was my most memorable. It was an early- morning raid on a suspected Taliban hideout where we expected to find five to eight Taliban members.

Our plan required a member of the assault force, our senior weapons sergeant, to move through the target compounds with the assault element, then up onto some high ground behind the target where he could provide over- watch during the detailed search that would follow the assault. The weapons sergeant selected the SPR Mod 0 as his gun of choice.

The reason the SPR is a valuable firearm to our soldiers is that it is small and light enough to be used as a traditional carbine for house-to-house action, yet still allows the shooter to reach out to 400 to 500 meters should the need arise. Our early- morning raid was just one of many such times the SPR was called upon to perform as it was envisioned and designed.

The raid went very well. We stumbled upon many more Taliban than we initially expected (we came across between 40 and 60), but the darkness and other factors played to our advantage. Chris, the weapons sergeant, had his hands full that morning (as we all did), but at the end of the three-hour battle he was unharmed and smiling contentedly with his SPR. He engaged multiple Taliban both within and without the target structures at distances ranging from a few feet to 300 meters. That's what the SPR was designed for, and it performed magnificently.



TIME ON THE GUN

I enjoyed the SPR Mod 0 upper that I received from PRI to review for this article; shooting the upper brought back a lot of good memories. The SPR is one of the softest-shooting ARs out there, due mostly to the excellent muzzle brake and the rifle-length gas system. The SPR makes rapidly engaging multiple targets at long distance possible, thanks in large part to the almost nonexistent recoil.

The PRI SPR I fired exhibited exceptional accuracy, and I felt like I was the limiting factor, not the rifle. The SPR's best five-shot groups at 100 yards came from Hornady's 55-grain A-Max, at .58 inch. Hornady 75-grain TAP came in at .7 inch, and the Black Hills 77-grain BTHP grouped at .91 inch.

I'm sure that the rifle is capable of much more—some days at the range are just better than others.

While the military occasionally makes some bone-headed decisions with its firearms, it delivered an exceptional product with the SPR, thanks in large part to the folks at PRI. If you're looking for a premium upper capable of handling trouble from the muzzle out to whatever range you're comfortable with, in terms of terminal ballistics, look no further than an SPR Mod 0.

The ammo

More often than not, when the military comes up with something worth having, civilians have to wait 20 or 30 years before it hits the surplus pipeline and ends up in their hands. All those wonderful CMP M1 Garands, M1 carbines, and 1903 rifles come immediately to mind, as do the Korea-era packs and canteens I hunted and camped with as a kid. Occasionally, a unique or utilitarian product ends up on shelves and in catalogs at the same time it rolls out of supply depots.

And that is the case with some of the best 5.56x45mm NATO ammo ever to come in a battle pack. Black Hills Ammunition worked for years, with first the U.S. Army Marksmanship Unit (AMU) and later the U.S. Navy, on a long-term project that resulted in MK 262 Mod 1. The project started out to develop ammo for competitors initially and morphed its way into the magazines of operators. Civilian shooters can buy that exact same round—it just comes in a much prettier box—for improved downrange performance, accuracy, and lethality.

Black Hills President Jeff Hoffman has long described the company as either "a big little company or a little big company" that started with and specializes in .223 and 5.56x45mm NATO ammunition. At last count Black Hills cataloged 15 different new-manufacture .223 loads, three new-manufacture 5.56mm loads, 12 remanufactured loads, and several military-only 5.56 loads. The round count is in the tens of millions annually and includes everything from very frangible varmint ammo to heavy-for-caliber, long-range ammo.

In 1996 a retired Army officer approached Hoffman about pursuing a newly announced AMU ammo contract.

"I told him we didn't know a thing about Army contracts," Hoffman said. However, the colonel did, and combined with the company's extensive .223 experience, Black Hills won the contract to produce 80-grain .223 ammo for 600-yard target work. The AMU wanted a certain velocity at a pressure that was within SAAMI specifications.

"I told them it was impossible, and it was, but we saved them 10,000 psi over what they were doing," Hoffman said. "We won the bid."

Because they have the best budget for ammunition development, and because it is their job to shoot really well, the rest of the military closely watches the AMU and what they shoot. In short order, Black Hills had secured ammo contracts for most of the other military service competition teams. Everyone knew war-fighters would soon follow in their tracks.

In 1999 Hoffman was approached by engineers from Naval Surface Warfare Center, Crane Division (NSWC Crane) about developing a load for an accurized, suppressed M-16 that was eventually called the MK 12 Special Purpose Rifle (SPR). The Crane SPRs were built from mothballed M-16A1 lowers and had 18-inch barrels.

Over the next decade, name and configuration changes were as rampant as the rifle was successful, and other services were quick to employ similar guns. The Marine Corps Squad Advanced Marksman Rifle (SAM-R) and the Army Squad Designated Marksman Rifle (SDM-R), not to be confused with the M-14-based Designated Marksman Rifle (DMR) and Enhanced Battle Rifle (EBR), are good examples of either straight copying of a great idea or dual evolution depending on whom you ask.

Despite the name, fore-end and stock configuration, optic choice, and camo pattern worn by the guy toting it, this new class of rifle needed new ammo that was both accurate and lethal out to 600 yards. Black Hills sent NSWC Crane a couple thousand AMU rounds as a starting point.

"We initially made a couple of changes to harden and militarize the round," Hoffman said. "We started with .223 brass and then went to mil-spec 5.56mm brass. We added a flash suppressant, and the velocity was bumped up 150 fps, too, so we were getting 2,700 to 2,750 fps at the muzzle."
[Show as slideshow]

Several bullets were used during the development process, including the 73-grain Berger, 77-grain Sierra MatchKing, and 77-grain Nosler HPBT. Black Hills finally settled on the MatchKing when Sierra agreed to put a cannelure on the bullet. Hoffman said there was no perceivable difference in accuracy between the different bullets in real-world rifles, but in test fixtures Sierra's bullet proved slightly more accurate.

"It was tough convincing Sierra to put a cannelure on that bullet," Hoffman said. "They were really concerned about destroying accuracy, but we didn't want a bullet stuffed back into a case to render a rifle inoperable. We are big believers in Murphy. If he can get involved, it won't happen in training; it will happen when some SF guy kicks down a door in Afghanistan."

Accuracy was exceptional, certainly an improvement over M855, though Crane's spec is still considered sensitive and Hoffman would not reveal the details. He said the accuracy spec is tighter than any other small arms round in the U.S. military's inventory. Some research revealed that the ammo had to hold MOA groups, or 3.5 inches at 300 yards, over five 10-shot groups.

"The max effective range [of the M-16A1] with the original M193 ammo was 460 yards," Hoffman said. "We've come a long way from that and have reports of successful engagements past 800 yards. I've shot out to 1,100 yards with it."

For the idly curious, with a 100-yard zero, MK 262 Mod 1 requires 37.25 minutes of come-up at 1,000 yards (elevation 2,500 feet), at least in Hoffman's rifle.

The name changed with each modification. MK 262 Mod 0 was adopted in 2002, Mod 1 came along in 2003 with the cannelure, and an improvement to temperature sensitivity came along in 2005. Hoffman said the last change came after Black Hills technicians noticed some failures to extract (FTX) in their test M4 and short-barreled rifles, and that it was the most difficult problem to solve.

"We initially thought the FTXs were possibly related to higher port pressures," Hoffman said. "The M4's port pressure is around 25,000 psi, much higher than the SPR due to the location of the gas port on the respective guns. We looked at brass, powder, everything."

It finally came down to chamber temperature. The test specification called for the ammo to be baked at 125 degrees for two hours and not exceed pressure limits when then chambered and fired. When Black Hills engineers started firing test guns far beyond the specified rate of fire, the chamber temperatures got much hotter than 125 degrees. In an extended firefight, soldiers could heat up their rifles with a few mags, and then during a lull in fighting, a chambered round would sit in a 200- or even 300-degree environment. That significantly increased chamber pressures and induced failures to extract.

"After we figured it out, I was surprised that it hadn't come up before," Hoffman said. "We've gone from bolt rifles to eight-round Garand clips to closed-bolt, select-fire rifles. SF guys never had an issue because they are trained to fire two or three rounds per target and very rarely go full auto."

It only took Black Hills 75,000 rounds to sort out the problem—a chunk of the 250,000 rounds Hoffman figures the company fired developing and lot-testing the load. Finally, the round was issued. Interestingly, the ammo always did meet specs, even the ammo that Black Hills engineers felt needed improvement—they just found a way to make it better. The Navy began changing test specifications based on what Black Hills learned—and shared—during development and testing. The improved round was a hit, no pun intended, with operators in-theatre, and usage went through the roof. Not only did the ammo perform well for its intended purpose—long-range shooting—but did equally well in short-barreled rifles like the M4 (14.5-inch barrel) and MK 18 (10.3-inch barrel), which leads to a discussion of lethality.

"The assaulters were stealing it from the snipers, so we had to make more," Hoffman said.

The MK 262 Mod 1 projectile is an open-tipped match (OTM) bullet, though it does not expand in the manner of a conventional hollowpoint. In fact, the hollow cavity is not there to induce expansion; it's there to put the majority of weight towards the projectile's rear so that it is more stable in flight and increase accuracy. Because it is not designed to expand and cause "undue suffering," that critical phrase in the Hague Conventions regarding ammunition, the Navy's Judge Advocate General Corps approved the round for use in combat. The same reasoning was applied to the Marine Corps 62-grain SOST round (MK 318), also an OTM design.

When the bullet strikes soft tissue, the heavier base comes around and causes the bullet to yaw, or tumble. The hollow nose cone breaks off and often the bullet fragments at the cannelure. This happens across a wide range of the velocity spectrum, which is why MK 262 Mod 1 proved effective in SBRs in addition to the longer-barreled SPRs. M855—or "Green Tip"—ammo was designed for battles with a body-armor-equipped army, hence the name "Penetrator." On unarmored targets, it just zips through like it was designed to do. MK 262 was a better option for the enemy the military was fighting in Iraq and Afghanistan, though the round obviously does not penetrate as much as M855.

I spoke with a good friend with multiple combat tours in both Iraq and Afghanistan. His experiences as both a Special Forces sniper team leader and assaulter offered a unique perspective on ammo performance. As a sniper, MK 262 was his preferred round (when he was not using 7.62x51mm NATO), and he said simply, "It's the best, most accurate round the Army has ever issued." When carrying the shorter SBR, he ranked Hornady's 75-grain TAP as the most lethal, followed by MK 318 and with MK 262 riding herd at third. Anything was better than M855 in a CQB environment.

"All 5.56 rounds suck out of SBRs, but MK 262 is way better than M855," he said. "The only time M855 shines is when you are shooting through intermediate barriers like car doors."

The public was first able to get its hands on MK 262 in the form of cosmetic blemishes, sold in bulk by Cabela's and other select Black Hills dealers. Every round is inspected, and, well, Black Hills had to do something with scratched and dented cartridges, though the imperfections are generally so minor that the untrained eye cannot see why they were pulled from military runs.

"The round developed a cult following, even packed as cosmetic seconds," Hoffman said. "So last year we started offering it to the public. The only difference is the packaging—it is the exact same ammunition as is delivered to the U.S. military—loaded to the exact same specs. The guy shooting iron sights at beer cans at 100 yards probably has no reason to shoot this, but a man that has the skill and firearm to extend the range, this is his round."

Sold in 50-count boxes for around $1 per round, with a rather mundane "5.56mm 77-Gr. OTM" printed on the label, there is little to separate it from other Black Hills offerings. But in the right rifle at longer ranges, shooters can really see a difference in accuracy, wind drift, and terminal performance. On the battlefield the same stuff in plain, 20-round cardboard boxes printed with "5.56mm SPECIAL BALL, LR MK 262 MOD 1" can be found in the packs of any soldier, sailor, or Marine looking to extend the range of his optically sighted precision rifle or increase the lethality of an SBR.

At question 8 , why are you asking for 500 yds MOA (that is 457 meters), you should be asking for the MOA at 300 mts since this is the normal limit engagement for the AR.
For further engagement range we should open a topic on Battle Riffles or DMR.

Same story for the people that at Service rifles topics start talking about Noveske and similar builds.

sir ,I know, but i am asking at 500yards because i feel that with evolution in assault rifle technology,one should be able to provide good moa atleast till 500 yds with a good scope .So that it can act as a good long range shooter as well with the weight and length of assault rifle.You can say this is one quality which i want to be in a futuristic assault rifle,that's why asking.

1 It's cheaper, the logistics chain is simpler and so on. So for example our military won't introduce two or more assault rifle types, but a single one, because there is at least minimum 80% commonality inbetween all variants.

2 It all depends on military, Polish Army considers using classical variants for infantry and special forces, while bullpup is considered more as a PDW for rear eschelon forces, armored fighting vehicles crews, for pilots, and of course for special forces for CQB.

3 Not known yet, however as far as we know, MSBS reliability is not worse than AK rifle.

4 Dunno but it seems to be very accurate and recoil is low.

5 Charging handle is in the upper part of upper receiver, it is non reciprocating charging handle type.

You can see charging handles of both classic and bullpup variant, actually upper receiver on both variants is exactly the same.

6 Yes, there are different variants of barrel designed, some are lighter some heavier, gas ejection can be regulated.

7 Like any modern assault rifle.

8 Sorry, I don't have exact data, but people involved in to project and testing says it's not worse than any other modern assault rifle.

9 Dunno but not much, MSBS is fully modular and disassmebling it for cleaning is very easy, for example taking off buttstock in classic variant is a matter of seconds.

10 Probably the same, AFAIK you can use any kind of muzzle device on it.

11 Yes, it is planned to have different callibers, just priority got the 5,56x45mm variant, there is planned 7,62x51mm variant, we also know about 12 gauge shotgun variant, other variants are also possible.

Here is 12 gauge shotgun variant of the MSBS, as you can see it's preatty much the same basic design as assault rifle, of course some changes in design are nececary.

12 Hard to say, there is a lot of secrecy about some aspects of the project.

What more I can say? I actually had opportunity to hold MSBS and several other assault rifle designs, and I must proudly say that MSBS in terms of ergonomics beat any competition hands down.
