How is it different from G2?

How is it different from G2?

It has a direct impingement gas system like the one on M16. G2 uses a short stroke piston gas system like on the HK 416. 716i will be more accurate and lighter and 716 G2 will be slightly more reliable and less prone to malfunctions as too much dirt doesn't enter its chamber. That said, if cleaned regularly, 716i is way better than 716 G2, especially for infantry, who may have to carry it around. Direct impingement guns are easier to clean as well.

DI systems are more reliable in mud, as there is no piston system that gets caked in mud.

How is it different from G2?

G2 has a Short Stroke Piston System while other has Direct Impingement System which is cheaper to manufacture, makes the gun lighter to carry and it is slightly more accurate than short stroke equipped M16/AR Type Rifles.

Other positive reviews of Sig 716i

From Small arms solution


From TFB TV


From Pew pew tactical


Bottom line: Sig 716i is highly reliable and very accurate. It can do sub MOA with match grade ammo and 2-3 MOA with standard ball ammo.
However, recoil is somewhat lower than standard AR-10 based rifles, but it is not much different from earlier versions of OFB R2. Later OFB added a huge muzzle brake on that, to further reduce the recoil.

A muzzle brake on a standard issue infantry rifle is a bad idea. If you're huddled up in a bunker or in a buddy pair performing CQB, your rifle will shoot hot gases into your teammates face. Also, say goodbye to stealth. You can gear the gun going off from miles away and see the flash from a long way off, in broad daylight.

PS: Muzzle brake redirects the almost the whole volume discharged gases sideways. Naturally, the gases are not slowed down at all and hence create a large signature, both sound and flash wise.

I agree with that part. But OFB has decided to put it on their R2 rifle, to reduce the recoil. Though it has its own disadvantages, but it is much simpler to implement. If they were being innovative, they could have gone with some kind of spring system in the receiver section, or a M4 style buffer tube in the back. If they were being super innovative, they could have tried something like balanced recoil system like AK 107. However, muzzle brake was the simpler solution without having to go back to the drawing board on the 5.56*45 Excalibur MK1C design which was scaled up to R2 rifle design within a short span of just 6 months. This 6 months breathing space was given to OFB by Mr. Parrikar since the army suddenly changed the caliber requirement to 7.62mm and was going to issue a global RFI.

For obf painting rifles in black rectify every issue in rifles like jamming, etc.

For obf painting rifles in black rectify every issue in rifles like jamming, etc.

Jamming issue was solved in Excalibur MK1C itself in 2015-16, with combined effort from OFB, ARDE and Army.

But army changed caliber requirement, so OFB came up with a scaled up version of Excalibur MK1C called R2.

Why army is buying ak 203 and sig 716 instead of obf rifles.?

 

[shuvo@y2k10]

Why army is buying ak 203 and sig 716 instead of obf rifles.?

Regarding Sig 716 is concerned, it was always meant to be a fast track purchase and rest 5.5 lac 7.62*51 mm was meant to manufactured in India by OFB. Also, army gave time in 2017-2018, to the OFB for R2 to mature and army is deeply involved in this project. On-on one, the Sig 716 is probably a better rifle in all major categories (being a DI system vs. a long stroke gas piston system of R2), except in the reliability with adverse use. DI rifles also require regular cleaning.

Regarding the AK203 rifle, it was always a political decision, and the deal at the present moment seems to be in jeopardy. Also, the R2 rifle from OFB is not its competitor, but TAR, Ghatak and FAB modified existing AKs in service are. Also,SSS defence is in contention in this 6.5 lac RFI even since this category has been moved to Negative import list.

Well there isn't much you can do to reduce recoil (and muzzle climb due to that) on AK since it is the way it works, the bolt carrier slaps violently to the end of the receiver to transfer excessive kinetic energy to the rearward part and finally to the shoulder of the shooter,
and if you mix it with the fact that AK's ;front-heavy; bolt carrier has made it a slightly off-centred rifle then with every rearward-forward motion of the bolt carrier it moves around its centre turning into further uncontrollable weapon on full auto.

some options that you have is (a) tune the gas system down from its default overgassed setting so that its bolt carrier doesn't slap to its rear end as violently as before, but it could potentially worsen the reliabe operation of the firearm (b) put a recoil buffer on the rear part of the rifle where bolt carrier slaps (This is what is done on Galil ACE) but that too is more or less a jugaad as with every shot the buffer gonna wear out and you may need replacement after certain hundreds of rounds fired

Muzzle brakes are experimentally proven to reduce recoil force and recoil distance. Many tests have been carried out in USA for a variety of ammunition. For example:

[shuvo@y2k10]

the bolt carrier slaps violently to the end of the receiver to transfer excessive kinetic energy to the rearward part and finally to the shoulder of the shooter,

Solution of this problem already exists in the form of a balanced recoil system where to counter the impulse of the bolt carrier moving back, a special rod moves forward at precisely the same time. Both counter balancing rod and bolt carrier are connected to the gas system and linked to each other via a gear.
This is implemented in AK107 and its civilan version Saiga 107.

Bottom line- it REALLY needs some decent optics to take advantage of, issuing it with iron sights is a pathetic joke being played on the infantrymen

In other countries this would be a scandal
