Ratings & Reviews
Great Bolt Carrier
by Michael -
Was a little skeptical getting this bolt carrier given there were no reviews, but I'm glad I went for it.
It cycles and fit great with my New Frontier Glock Lower, it cycles brass and steel without any issues.
Awesome Product /Customer Service Beyond Reproach
by Frank -
Awesome product!! purchased this for use with a sylvan arms Glock Mag conversion insert. I initially attempted to use this with a PRI Gasbuster charging handle, but due to some non mil spec changes in the charging handle, it would not catch the bolt properly and jammed. I contacted Paul at FM and he helped me out. They have incredible and prompt customer service and are willing to listen to your problem and do everything necessary to get your gun running right. I highly recommend their products and will certainly purchase FM products in the future.

I haven’t finished my build yet so I can’t comment on the performance of this BCG. But what I can say is that it is solidly built and looks cleanly manufactured. I did have a hiccup with my BCG not having any of the engravings. Primary arms got me in touch with the owner of Foxtrot Mike. He’s a great dude and took care of my problems right away! I would definitely recommend FM products and I’ll likely buy more in the future.

High Quality Product & Top-Notch Support at FM
by B. Smith -
This is a high quality BCG. At first, I was experiencing jams every few rounds. I contacted FM for support. Paul at FM provided top-notch customer service. He diagnosed and instructed me on how to fix the issue I was having. It wasn't even their product that was causing the issue but he went out of his way to help. I will definitely be choosing FM 9mm bolts from here on out! Thanks Paul! *Note: You need to sand down the ejector on TN Arms lowers to work with this bolt. Since then, I have had 0 jams.*
Great for Fostech trigger
Excellent bolt, Correctly cut to work with Fostech Echo 2. Well made and great price!
WILL NOT WORK WITH FORWARD CHARGING UPPERS!!
by steve -
Primary arms needs to let people know this will not work with forward charging uppers. I bought a new upper and put this bolt in it and it would not function. I did not notice that it was different from the one that came with it as I was not looking for a difference. I damaged my charging handle before I figured out what was wrong. Three stars for bad description. The part is top quality and Im sure I would give it 5 stars if I had a rear charging upper. I hope PA will add to the description.. WILL NOT WORK IN FORWARD CHARGING UPPERS!! Love Primary Arms, love Foxtrot Mike . FM is going to send me a new charging handle and I wrote PM about changing the description so I hope to see that soon.
From PA: We're very sorry for the confusion and we'll update the page accordingly.
May or may not work

I bought this for a new build that featured a MAS Defense completed 16" 9mm upper and the Stern Defense Glock mag conversion. The FM bolt would not extract, nor push the rounds into the barrel properly, often crushing the round from the side, or jamming the next round under it, failing every 5 rounds or so. I had a Spikes Tactical BCG from a 9mm pistol build, so I swapped them and my Stern/MAS Defense set up ran flawlessly. I tried the 16” and FM BCG on my pistol lower and got the same issues. I put the FM in my pistol and fortunately have not had an issue since, tho only put 200 rounds on it since. I had high hopes for this to be a plug-and-play build but it wasn’t, but fortunately I had the other build to swap parts between. Gave it 3 stars because it wasn't a complete trainwreck, but if it failed my 10.5" I would have given it a 1 star. Might play well with a Foxtrot Mike lower, but buyer beware if you have another set up.
