Questions & Answers
on the M16/M4 Bolt Carrier Group ,,What does it mean by No Hammer?? Expert Answer

It means it will not come with a hammer for the trigger group. Some of the FailZero bolt carrier groups come with a nickel boron coated hammer, but these models will not come with that hammer.

Will this BCG work with a 350 legend? My understanding is the 350 uses a standard 5.56/223 bolt. Expert Answer

Yes, technically the .350 Legend can use a standard AR-15 bolt carrier group.

Decent bcg by Just some dude., October 24, 2019
This bcg is a great find at the price. Remember this is EXO nickel boron with with a black coating applied over that wears off on contact points. I think it looks cool as it brakes in, but some might get bent that it loses its prettiness. The gas key...

looks pretty by eagle eye, October 29, 2024
No doubt this looks good. Only time will tell if it stays pretty. Cleaning it seems harder, you can see every little gunk unlike the black factory BCG. Also not as easy to clean as you would think, carbon seems to stick to it pretty good and I leave...

Runs like a champ by Jackal, May 30, 2021
I have one of these in my AR-15. I used a BCM extractor upgrade kit, and a milspec hammer spring (not sure if nessessary), but my AR-15 eats steel like it was brass. I shoot brass and Wolf steel loads with no problems/ ftf. These things are solid. Th...

Awesome finish by Banana, April 4, 2020
I’ve only shot a few hundred rounds so far but this bcg works great. The nickel boron coating is very easy to clean and requires minimal lubricant. It also disassembles very easily for quick and easy cleaning. Highly recommended
