ULW Rifle Adjustable Buffer System for AR15-223


(1 customer review)
  • Drop in assembly
  • Low reciprocating mass
  • Adjustable recoil spring preload with included spacers
  • Steel BCG recommended
  • Adjustable gas system required
  • Both pieces (including spacers) – 2.5oz
  • Reciprocating piece – 1oz


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.

Although some customers have used our recoil system with aluminum and Ti carriers, we have not personally tested this and can not recommend the use of our recoil system’s with those carriers
