JP Enterprises Stainless Full Mass FMOS Bolt Carrier
Excellent product, still lighter weight than a standard full mass M16 BCG, excellent nitride finish, cycles smooth as butter, gas ring seals perfectly with next to no friction. The burnished bore is outstanding. I recommend for a higher end build vs a budget build

This is far and away the best BCG on the planet, this will be my second one. Shipping is a little bit of a bummer because they still need to re-ship it out to me.

I've had this for 4 years and I can't say enough good things about this BCG. Def worth the buy and it's a work horse. I run this thing hard. I have about 5000 rds and about 2000 of that is suppressed. I actually had my first malfunction just the other day, failure to extract, but it's mainly due to it not being clean and lubed. I purposely haven't been cleaning it at all just to see how it'll do after shooting it suppressed for months. But it works fine now after a good cleaning. Pretty legit. It is duty rated if that's what you're looking for. The finish allows it to be cleaned pretty easily but it's just an awesome BCG. You get more than what you pay for with this.
Pros:
durable
reliable
Cons:
None
Best Used for:
hunting
Home Defense
Duty / LE / military

I went ahead and ponied up the money and got this BCG. Excellent craftsmanship and it seemed to help with my rifle over gassing. Got a great finish easy to clean. Plus I’m happy that I’ve got my amateur home built rifle functional. I’m ready for the EMP, zombie apocalypse, communist invasion. But generally good solid weekend warrior time at the range.
