INSAS Rifle, LMG & Carbine

[W.G.Ewald]

A little off-topic, but interesting:

New 5.56x30mm Cartridge from India « Daily Bulletin

Remington Fireball cartridge was designed for this bolt-action pistol.

INSAS LMG has very high rate of fire and quite accurate in full auto compare to Bren..

Indeed a drum magazine in western style would offer gr8 boost in fire power..

INSAS LMG dont have a quick barrel change option unlike old bren
But army still love its Bren LMG because of its round ,so why did't the OFB made a 7.62mm NATO insas LMG

INSAS AR

?? Is this an AR version of Insas ,because as far as i know INSAS is SEMI Automatic

AR means Assault Rifle. LMG means Light Machine Gun.


So, we have INSAS AR and INSAS LMG. This one is an AR. INSAS AR is available in both fully-automatic as well as semi-automatic. I don't know what this one in the picture is, but to my best guess, it is semi-automatic.

I thought It was battle rifle just like SLR

SLR means Self Loading Rifle, i.e. a rifle that does not require to be manually cocked, like in Lee-Enfield. Normally, when we say SLR, we are talking about the FN-FAL clone, but going by definition, INSAS is indeed an SLR.

@Kunal Biswas, @Ray, correct me if I am wrong.

I think rifle needs to be fully automatic to be called an Assault rifle like AK47 .. and all semi auto rifle comes in battle Rifle category like your FN FAL,G3 ,INSAS etc , although not many 5.56 mm rifles are semi auto like INSAS that's why it confuses a lot for people to call it an assault rifle or battle rifle...

FN-FAL also comes in fully-automatic. AK-47 is an assault rifle, but can also be loosely termed a sub-machine-gun. I don't think being fully-automatic is necessary to be called assault rifle.

The original assault rifles were definitely capable of full-auto mode.

A good discussion here:

Correct me if I am wrong

Insas has a 3 round burst mode and single shot mode but full auto mode is removed due to doctrine and not due to technical issues.

Also, a battle field rifle is more powerful and has a higher caliber (7.62x51 mm) than an assault rifle. HK G3 can be classified as a battle field rifle.

Sub-machine gun is generally pistol caliber.

And, any thing within can be classified as Assault rifle.

Any, rifle with larger than pistol caliber but having a smaller dimension ( barrel) than a assault rifle is called a carbine.

I feel being fully automatic has any thing to do with the classification.

A battle field rifle can be made fully automatic if recoil is not an issue.

We cannot divorce doctrine from technicalities. Yes, the fully-automatic INSAS AR was not preferred because of doctrine. However, shooting fully-automatics from an INSAS AR would either overheat the barrel and jam it, or would require heavier barrel to prevent it from overheating, making it just about as heavy as an INSAS LMG. So, yes, it was doctrine, but also because of technical issues.

Another thing to consider is the Soviet Army, with widespread conscription, where "one bullet one enemy" logic is not possible due to lack of well trained troops. They preferred to retain the option of fully-automatic Kalashnikovs.

What is calibre?

In guns, particularly firearms, caliber or calibre is the approximate internal diameter of the barrel, or the diameter of the projectile it fires.

Let's have a comparative look:

So, an AKM, an AK-74, and an M-16 have smaller calibres than a pistol that fires a 9mm cartridge.

@Kunal Biswas, @Ray, correct me if I am wrong.

Self loading means automatically ejecting a shell and chambering the next round from the magazine. It can be in the automatic or semiautomatic mode of firing.

A semi-automatic rifle is a rifle that fires a single round each time the trigger is pulled, uses gas, blowforward, blowback, or recoil to eject the spent cartridge after the round has travelled down the barrel, chambers a new cartridge from its magazine, and resets the action; enabling another round to be fired once the trigger is depressed again.

An automatic rifle is a type of magazine-fed rifle that uses either its recoil or a portion of the gas propelling the projectile to remove the spent cartridge case, cock the rifle, load a new cartridge and fire again repeatedly, as long as the trigger is held down or until the magazine is exhausted.

This link shows the firing cycle of a semi automatic weapon.

It is animated and so will clearly explain the cycle step by step of each action that takes place from chambering the road, firing, the bullet moving out recoil, ejection and re-chambering the newt round.

OK, Insas has/ had issues with automatic firing,
But, M-16 is also semi-automatic rifle.
And again due to same doctrine it is semi-automatic.
But, again will it be classified as AR?

Also Caliber was a wrong term.
I meant 7.6x 51 mm vs 7.62 x 39 cartridge.

Essentially low powered cartridge.

What I wanted to say is distinction between a battle field rifle, assault rifle and sub-machine gun is the bullet sizes ( for want of the technical term for it) and not whether it is full-auto or semi auto or single fire.

M-16 is also available in fully-automatic.

They used them in Vietnam, IIRC. @W.G.Ewald, please confirm.

Ok, a battlefield rifle and an assault rifle are essentially guns that fire spinning projectiles, but a sub-machine-gun might or might not fire spinning bullets, depending on whether it is a rifle or a smooth-bore.

Yes, a sub-machine-gun will be ideal for a shorter range and the length of the bullet will be smaller, even if the diameter is bigger.

Secondly, I do not know the difference between a battlefield rifle and an assault rifle. Can you clarify that a bit?

I have very limited knowledge about this.
but, below is a wiki link on battle field rifle

Yes, I saw my first M16 in 1966 while stationed at USARJ (Japan). Two years earlier the M14 was the issue rifle and I qualified with that rifle. By 1966 the M16 was replacing it in combat theater.
