Running this with the standard Mean Arms upper and a P lifter, and it has a noticeably softer impulse than a standard carbine buffer and spring with 135PF ammo. If you already own a Mean Arms upper, this buffer system will elevate your experience even further.

The buffer working great with Mean arm upper ! Only one thing I can suggest is are you guys going to make a short stroke version of it?

We have tried short stroke and only see a benefit of it in direct blowback guns with heavy reciprocating mass.

I felt an immediate difference by just pulling the charging handle back. This is a must upgrade for your Mean Arms upper! By the way I’m using the 16 inch version.
