INSAS Rifle, LMG & Carbine

[DivineHeretic]

sir then how come INSAS rifle range 400 meters and INSAS LMG 700 meters , is it relates to the barrel length of the LMG ?

Precisely. All other factors remaining same, the longer the barrel, the greater the range.

You've read about the three Kinematic equations of motion. Well, they are the fundamentals to explaining this.

where s = displacement (s0 = initial displacement), u = initial velocity, v = final velocity, a = acceleration, t = time

Now, let's take the 1st equation: (note that initial velocity = velocity of the gun =0)

If a barrel is longer, the bullet spends more time (t) in the barrel. Consequently, the acceleration (force) acts on the bullet for a longer time(i.e. 't' increases). As a result, the bullet exiting the barrel has a higher velocity (v), and thus a greater range.

You could also use the 4rd equation to explain the same phenomenon.

As the length of the barrel increases, the distance (displacement) traveled by the bullet inside the gun increases (i.e. s increases). As a result, the distance for which the bullet experiences the acceleration (a) increases. Thus V increases, as can be found from the equation.

It's really that simple.

Thanks guys for explaining it.

So in anti terrorist operation INSAS LMG with scope is great asset.

 

[Kunal Biswas]

Just lack an drum magazine option ..

not necessarily. a lot of factors come into play like

range, proximity to civilian population, type of tactics being employed. each situation calls for a different tactic and a specified weapon.

 

[sayareakd]

Just lack an drum magazine option ..

Yeah we discuss that sir, but they want to save ammo.

 

[Kunal Biswas]

Not to save ammunition, But to keep it lighter as its valuable under patrols and charging purposes, Sir ..

The need for drum magazine arise when its mounted on vehicle and fixed positions, MMG is not available in smaller formation and their is always need for its special ammunition and spares separately from other firearms ..


========================

For example >>

Lighter under street fight conditions

Lack suppressing fire power over vehicle and fixed positions, Unlike MMG ..

Yeah we discuss that sir, but they want to save ammo.

 

[SafedSagar]

That is one awkward looking pistol grip.

 

[ALBY]

In the GSQR they could have mentioned that instead of an semi SOPMOD AK they need a SOPMOD VZ58.

Instead just going to make a clone of AK and renaming it, OFB should have placed atleast came up with some innovative modifications;
1-Integrated rails in the receiver to mount scopes.
2-Rear sight at the very end of receiver like that in M-16/4s or like in new AK-12
3-AK-74 or M-4 or the recoil compensator used by Russian SF instead of the age old slant muzzle brake.
4-90 Degree gas block instead of the old 45 degre gas block.
5-Instead of Fixed or folding stocks it should have M4 type collapsing butt stocks with recoil buffers just like the one we spotted in the DRDOs multoi cal weapon.
6-A better fire selector just like the ones in VZ,AK12 or those American gunsmiths shows us in youtube.

Something like this ....

It's a bullpup kit for an AK 47 from Center Balanced Systems

where is the trigger of the ubgl situated?

 

[Kunal Biswas]

The trigger is located at forward, Watch the vid for more information ..

Instead just going to make a clone of AK and renaming it, OFB should have placed atleast came up with some innovative modifications;
1-Integrated rails in the receiver to mount scopes.

Removable dust covers with rails and sights require very high quality machining (finnish Valmet is an example). Integrated rails work very with those guns where the upper does not move with respect to barrel, i.e. the upper/lower style construction of m-16 family. The only practical place to mount sights on AKMs are upper hand guards, but rails could have been mounted like Excalibur.

2-Rear sight at the very end of receiver like that in M-16/4s or like in new AK-12

See above.

3-AK-74 or M-4 or the recoil compensator used by Russian SF instead of the age old slant muzzle brake.

Not needed on an AKM. The ammunition contains less powder than 5.5.6 NATO. It will needlessly increase cost.

4-90 Degree gas block instead of the old 45 degre gas block.

AKM's low velocity bullet does not create a problem with 45 degree gas block. Something they should fix on MCIWS.

5-Instead of Fixed or folding stocks it should have M4 type collapsing butt stocks with recoil buffers just like the one we spotted in the DRDOs multoi cal weapon.

Buffer stock is useless on a gun which does not require a buffer spring in stock, unless you meant a telescopic butt stock. The SIG style folding stock as on Excalibur is a good choice. A folding telescopic butt stock would have been a better choice. No modern gun is designed with a buffer spring in stock, if they did it with MCIWS, it is a very very bad choice because you cannot make a folding stock version of the gun.

6-A better fire selector just like the ones in VZ,AK12 or those American gunsmiths shows us in youtube.

Should have gone with an INSAS style selector. Anything else slows down training and adoption.

@Kunal Biswas Sir, do you know about the system reported in this news item :

[Kunal Biswas]

It is not yet seen here, When it will be available it would be nice ..
