Works great on my build. 4/5 because recoil makes the spring rattle around a little bit. but produces flawless functioning.
Won’t Allow Full Travel
Building a DPMS .308 using matched Matrix Arms receivers. Wanted a fixed stock and looked at Luth Ar for some time. Ordered this kit to go with the stock which was an easy install. The problem is the bolt won’t come back far enough to properly lock on the face, it locks on the carrier lip and won’t go back any further. Tried another functiong upper and same problem. Tried several different rifle length springs and same problem. The buffer measures 6” which is 3/4” too long for full cycle. Seems to be some spring stack to go along with that. Running out of good ideas to make this work. AR 10s are a true challenge.
Red Faced Time
I want to apologize to Luth Ar, Primary Arms and anyone who read my 6/23 review and thought I knew what I was doing. If I could delete that I would.
<br>The Luth Ar buffer kit I was using on a .308 build was actually for an AR15 and I should have realized this when the buffer measured 5 7/8. No that won't work with the longer .308 bcg. Given the right kit function is perfect. Luth Ar is a quality product worthy of more careful evaluation.
<br>Never underestimate the power of ignorant.
Worked perfect on my BUSHMASTER 308 (DPMS style)
Installed this on my Bushmaster 308 and it works amazing. The install was ridiculously easy. I'm running this with the LUTHAR adjustable stock and with a rifle length gas system and this heavy buffer, its really tamed down the rifle's feed back.
Not a good spring/buffer assembly.

The only thing thats redeeming about this is the tube itself. The buffer and spring are reminscent of the noisy POS that was in our M4's in the military. Sounds and feels terrible.
