Not much of a review here, I’ve only put about 200 rounds down range with this system, but it does seem to function very well. I just built a full Aero/Ballistic Advantage 8.3†AR9, and this is the buffer/spring I threw in, with the intention of putting in a super safety down the road. The only issues I had seem to be ammo related, tried multiple 147 grain rounds, and the one that fired without issue was blazer brass, has feeding issues with Remington UMC and Fiocchi 147’s, but it ate the blazer and regular ball with zero issues. The buffer/spring did its job well, felt recoil was lighter than expected, cycling felt smoother than a standard setup, and like I said, functioned flawlessly with ammo that gun seemed to like. I’ll update this review whenever I throw in a super safety and run this build over 1k rounds. So far I’m quite happy with it.
