Will this work for angstad ar9 ?

Bought one and used 7.4 weight for a total weight of 21 ounces ( bolt+ buffer) on my angstad ar9. Functioning smoothly and softer recoil. Just follow the instructions on how to assemble the buffer. Highly recommended.

Most Recent Reviews Searching for that perfect recoil pulse by Greg Weems, Verified Owner, September 26, 2025
