Telescoping stocks that can vary the length of pull are ideal for body armor, cold weather clothing, female officers etc. The use of the AR-15 grip without a buttstock can be utilized in breaching, C.Q.B., in vehicles and when maximum maneuverability is essential.

While our competitors claim, "CNC machined aircraft aluminum", in reality they cast their adapters like some sort of a toy, machining only the holes. note that the term "aircraft aluminium / aerospace aluminium" usually refers to 7075 stock, not cast or 6xxx series aluminum.

We intricately machine the entire S2AR adapter from a solid billet of 7075 T-6 aluminum. Best of breed, simple, one piece... indestructible.
