Working without issue with ASC colt style mags, put a couple hundred rounds in with it so far and running great!

Just finished my AR9 build. Used this BCG in combination with a mil-spec upper, 5" FTM barrel, mil-spec lower with colt conversion block and ASC style mags. Also used a JP heavy buffer spring, FTM 9mm heavy buffer and Eotech XPS. This combo cycled flawlessly during its first 200 rounds. Both my buddies were droolin...THIS THING IS AWESOME!
Works great for my build.

Got this to jump start a PCC build idea ive had an itch for, the build is a spikes tactical upper & lower (trigger assembly as well) for Glock mags,FTM barrel & buffer parts, this BCG had no reviews a few months ago when i bought it, finally completed the build, ran a Glock big stick in it with federal 124gr fmj, ran 2 mag dumps back to back, and no issues with first 200 rounds.

Not for FM Products receiver set

This may be a decent bolt, but it will not cycle in my FM Products receiver set.

Bolt runs perfectly with Mean Arms EndoMag 9mm PMAG conversion kits.

Came Quick as always from PA, A little oil 5 rounds then 3 mag dumps, Ate em up and spit em out. 2 more stars
Will not hesitate to buy another.
Runs fantastic. My first 9mm build and I am glad I went this route. Almost all the parts are from Primary Arms.
