Does anyone know if LWRC will be offering the after market piston conversion for other upper receivers in the future? I heard the stopped doing that for a while.

It has yet to be determined when/if we will offer that again.

One criticism I have heard about pistons is that people complain that the gases are vented along the handguard. Thereby causing hot/dirty gases to burn, heatup, and dirty the rail system and your hand.

Can anyone comment on this?

The gas has to go somewhere. Better to have it under the handguards than in your face. :shock:

I agree, but why not vent the gases forward (direction of the bullet)? Where do the gases vent on the other piston driven rifles, does the gas venting on the LWRC result in the handguards getting too hot, and resulting in damage? Do the gases burn your hands during a prolonged firing session?

The gas has to go some where. Venting to the sides is more effcient then venting toward the muzzle. The carbon build up on the rails is noticable, but easily cleaned up. The impact of the heat generated from the barrel is far more an issue than the vented gas.

In response to burning your hand, absolutely not. One of our party tricks durning a demo is we will actually remove the top rail and hold a hand over the piston while firing.* All you really feel is a puff of warm air. Nothing crazy.

As far as dirty? Sure your hands might get a little dirty. They should. If you're not dirty you're not doing it right :wink:

Welcome to the kinder, gentler LWRC forum. Nowadays we dont bash dudes for not using the SEARCH button.

Answer: The IAR is a MACHINE GUN. That is what makes it the IAR. Therefore, since it is a newly manufactured machine gun, by law, it is not available to the general public.

The IAR is being developed for the United States Marine Corps. LWRCI is one of several manufacturers vieing for the contract. The closest the civilian market will get is the M6A3.

Trent.... IAR is currently available but not for sale to non-agency/institutional buyers. If your agency/unit is looking for IAR, please call the Office and ask for Military/LE Unit Sales.
