Are you looking for the right shaft for competition or sports? It fits any standard AR-15 assembly. For manufacturing parts of an AR-15, stainless steel is hardened to 26-32 RC and stress-free.
A closer look at the top of the receiver reveals that it is made from certified 7075-t6 aluminum forgings. Also, the end of the barrel is covered with an A2 birdcage flash hider. As for the chamber, it goes according to Type 2 - 6.5 Grendel. Aviation steel is used to make this barrel's AR-15 gas system kit. The handrails are medium-length bars with a free float. They are made from aircraft-grade aluminum with a black anodized finish. Also, there is a dust cover and a particular system to help the shooter move forward. It is important to remember that the barrel is compatible with 0.136" arm depth bolts. The standard 7.62x39 will not fit. When buying a barrel AR 15 kit, remember that no BCG or charging handle is included. All accessories will have to be purchased separately.
