Nice BCG

by

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.

Fawless Operation/awesome customer service

by

First and foremost the m16/m4 full auto BCG will work with an AR15, so rest assure if your second guessing compatibility with a civilian semi-auto ar15. Next the BCG shot flawlessly with no issues and clean up was as advertised, short an simple. As always PRIMARYARMS is awesome, I had ordered the AR15 version but then quickly learned that the full auto is compatible with an AR15 and I made hasty last second exchange before shipping and customer service was there to make the exchange happen before my order went out the next morning morning. Thanks PRIMARYARMS!
