- Drop in assembly
- Low reciprocating mass
- Adjustable recoil spring preload with included spacers
- Steel BCG recommended
- Adjustable gas system required
- Spring NOT INCLUDED
Designed for rifle length buffer systems and works with standard and lightweight steel bolt carrier groups to help reduce the primary recoil of the weapon. Additionally, you can reduce the preload of the recoil spring with included spacers. This reduces the speed of the bolt as it goes back into battery. This system requires an adjustable gas system. Failure to follow the above criteria may result in poor operation or damage to your platform.
