The AR Gas Vent is a unique product that addresses the problem of gas blow back when firing a suppressed AR-15 rifle.  Back pressure caused by suppressor use sends gasses and lubricants back into the user's face and can prevent effective engagement of targets after just a few rounds being fired.  It is difficult to effectively shoot at a target when your eyes are watering or shut from hot/irritating propellant gases, or when lubricants are being shot back onto your eye protection.

The AR Gas vent helps redirect a large amount of gas away from the shooter's face by creating a large channel which vents gas away from the upper receiver.  When used in conjunction with a charging handle which has been RTV Sealed, gas blow back is VASTLY reduced.

As a big fan of suppressors on AR-15s myself, I find this product to be invaluable.  It does have one minor caveat in that the forward assist's functionality is removed. However, I follow the EAG Tactical/Pat Roger's way of thinking:  If a round doesn't want to feed, eject it and feed the next one and therefore, have never used the forward assist in years of competition and tactical carbine training.

I've also noticed that the gas vent works great even when firing without a suppressor on!

     NOTE: The AR Gas Vent does not provide the function of the forward assist.
