Harrison Gunworks AR Super Saftey D2 Straight Kit

Required Components: M16 Pattern BCG, Low Shelf or M16 Cut Lower (Machining services are available for those with High Shelf and Colt lowers), Dead-Blow Buffer Weight (exact weight will depend on the caliber, barrel length, gas system, and if a silencer is used or not).



Note: It has been found that firearms with a barrel length shorter than 10.3in have had reliability issues when running the AR-SS kit. We recommend installing the parts on a firearm with a barrel length of at least 10.3in to maximize reliability. We cannot guarantee perfect function on barrels shorter than 10.3in.

​

Parts included: Replacement Milspec Flat Trigger, Safety Cam, Safety Lever, Rounded Detent.
