Great bolt. Will not work with an auto sear.

In general, this bolt is fantastic, especially for the price. It functions in semi auto like a champ. No failures whatsoever. Unfortunately, I bought it to use in a registered machine gun. It is not full auto capable.

High quality AR 9mm bolt

This is the high quality AR 9mm bolt that fits perfectly on my old Colt Sporter LightWeight with minimum modification such as removing magazine blocks, replacing a standard bolt lock, and then purchasing a new EndoMag 10/30 magazine. I shot 50 rounds with no issue, and it looks better too. Other brands either did not fit or required to change the new hammer and remove the sear block.

Better PCC BCG

Replaced United Defense bolt in AR-9 and eliminated bolt jamming rounds in chamber problems - a better overall design wrt round pick up and ejection too.

Just Works!

Quality product.

Very Nice Quality, Why Pat More

I am no engineer but the 9mm bolt seems simpler than a 556 bolt and those seem to cost less than most 9mm bolts. The FM bolt is does not skimp on fit and finish. I used this on my 2nd 9mm AR for Glock mags and tried the JP 9mm spring. Once you pop out the weight this functions perfectly with this system. Very happy with results using this bolt and magpul mags.

Great 9mm BCG

Used in a recent 9mm build, functions flawlessly, would use again without hesitation.

Great bolt

This Bolt is awesome! I would rate FM mike as outstanding quality bolt and if you have any issues they are John on the spot to answer question and take care of the issue. I got this bolt and have put hundreds of rounds down range my a little over 1000. I have been shooting it for a year now in a PCC shooting IDPA with there handguard and barrel. Built upper would have been the way to go. I wish I would have gotten one of their lowers and spikes lowers are not great with bolt hold open... waiting for their 45acp lowers to come out now to build 45acp PCC or pistol not sure yet which one. Thanks for a great product!

What the...IT WORKS?!?!?

This BCG boggles my mind. You mean a 9mm BCG that actually works right out of the bag without modifications, buffing, polishing, more buffing, more polishing, and more buffing, and then some more modifications? I've never bought a 9mm bolt that I didn't have to tweak is some fashion. This one dropped right in and gave me 200+ rounds without a single hiccup on the first day, and more after. Still, not a single ftf or fte. I'm impressed, and I will buy more. Using it in several different Glock adapter-fitted lowers, with barrels ranging from 4.5-16 inches, and the all just eat up ammo.
