Fail zero EXO(Nickel Boron coated ) M16 bolt Carri

As always, good deal's good service and, top of the line products.
Nice BCG
by M
Built well, and functioned perfectly dropped in for 200 rounds so far. Expected the coating to be a bit slicker to the touch, and to completely wipe clean. It doesn't though, and you still need to do a tiny bit of scraping on the back of the bolt. Everything else wiped right off. If your looking for a bcg this is a good buy. If you already have a functioning bcg, I would only buy it if I had spare cash I was looking to spend.

Can't say a whole lot just built the gun. Seems to be a very well built bolt assembly. Even the gun shop that looked at it said it was a quality piece.

Excellent product and great quality. I tested as soon as i received it, runs flawlessly. It looks to be lubed all the time without adding lube :)
