Griffin Armament SN-ACH(TM) - GEN 2 : The SN-ACH(TM) (Gen 2) (Suppressor Normalized Ambidextrous Charging Handle) is a patented, modernized, feature filled charging handle that will satisfy any AR15 user. The SN-ACH(TM) - Gen 2 features an improved gas check groove and an improved, forward-facing 60Adeg 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(TM) 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(TM) creates a tighter seal between the handle and your upper receiver, resulting in decreased gas leakage at the rear of the receiver. Configurable levers were also added so that a user could choose to run the included large lever, which works with gloved hands, or purchase and modularly use the smaller levers (available separately) without having to buy an entirely new handle at an excessive cost. The bolt carrier engaging hook features durable reinforced geometry for 30% increase in strength over milspec handles and approximately 3 times as strong as inferior 6061 handles which routinely break under hard use. Fitment bearing surfaces on the handle mating ensures reduced wobble fitment with the AR15 and AR10 upper receiver. The handle is made from 7075-T6 aluminum and hard coated for optimal wear resistance- the Griffin SN-ACH(TM) (Gen 2) is the finest charging handle available for the AR series family of firearms. FITMENT: SN-ACH(TM) 15: Fits all typical AR-15/M-4/M16 family firearms (1.3 oz weight)
