This AR-15 complete 9MM bufferless pistol upper has a 10.5" M4 barrel with a 416R Stainless Steel finish, and features a 1:10 twist rate, with a blow back gas system. It includes the V2 10" MLOK split rail, an M4 flat-top 7075 billet aluminum upper receiver, a bolt carrier group, a flash hider, and Gen 2 Side Charging handle, and will fit on a mil-spec AR-9 Bufferless lower.
Using this upper receiver, no buffer assembly is required! A picatinny (1913) folding or fixed stock can be used. The kit includes a receiver plug and picatinny backplate that replaces the buffer assembly. You CAN use your existing lower receiver without issue.
