The SN-ACH (Gen 2) (Suppressor Normalized Ambidextrous Charging Handle) is a patented, modernized, feature filled charging handle that will satisfy any AR15 user. The SN-ACH – Gen 2 features an improved gas check groove and an improved, forward-facing 60 degree gas vent that reduces gas in the face of the shooter when using a suppressor by ejecting it forward and to the side of the firearm. The revised Gen 2 SN-ACH also receives a beveled rear shoulder to capture gases escaping from the rear of the receiver and redirect them forward and to the sides instead of into the shooter’s face. Improved fitment and machining of the Gen 2 SN-ACH creates a tighter seal between the handle and your upper receiver, resulting in decreased gas leakage at the rear of the receiver.
