AMAZING BCG
First time breaking in my build and I couldn’t have asked for a better BCG along with all internal parts from Stag. Put 200 rounds through her and not a single misfire. Thanks !

Nickel boron BCG
This BCG cleans up easily when using in a suppressed application. STAG quality at a reasonable price.

5.56 nickel boron BCG
Bought this BCG a few months back and waited to write a review until I had a chance
to put a few rounds down range. I have put around 1500 rounds through the gun and this BCG has functioned flawlessly. I do not run my weapon systems dry so with that said if you properly lube your gun, failures are drastically reduced or are non existent with most quality built BCG's. Where this carrier shines is in its ease of maintenance, with a little clp on a rag or a solvent wipe the carrier comes clean with no real effort involved. I use slip 2000 and the BCG runs like it's on ball bearings.i experiencedo no failures to feed, no failures to fire, and no failures to eject. I upgraded my stag left handed
Carbine
With this BCG and believe
that this was one of the best upgrades I could have done. Definitely worth getting one. My only complaint would be the price, just wish it could be a little more in competition with their right handed
BCG's. With that said Stag is one of the only dedicated left hand manufactures out there building quality parts for us lefties, so I look at the price as an investment in my shooting experience. -

Nickel boron BCG
SLICK, this bolt works great. I shoot a suppresser most of the time so my rifle gets nasty on the inside. This bolt cleans up with a wipe of a solvent wet cloath.

Nickel Boron Coated Bolt Carrier Assembly - Left Handed
This item more than exceeded my expectations. Being a left handed shooter, left hand accessories are difficult to find. This item improved my shooting along with less bolt malfunctions. Clean was a lot easier as well. This item worked so well, I purchased a 2nd one for another AR- 15 I have. Great product.
