Great quality for the price
by Isaac H -
This BCG has a nitride finish inside and out. The nitride finish is slicker and harder than chrome lining for those of you complaining. This is the best price I have seen on a nitride BCG.
Buying another one now before the price goes up
Sleeper BCG.

A nitride carrier bcg for 70 bucks! Bolt is parkerized mpi stamped. The fit and finish is actually very good. The o-ring is a little stiff. I pulled mine out and it cycles perfectly. This is a good budget option.

I got several of these today and I'm not sure it has any coating. It looks like the whole thing was spray painted with a .99 cent can of paint from Walmart and touched up with a brush. Not sure if I want to trust them or not.
NOT chrome lined?
by D Trent
Just received it and it looks to be a quality part, however the carrier is NOT chrome lined. Don't know if this will reduce the reliability or longevity? Time will tell.
This would probably be a great piece to have as a spare, as I got the whole carrier group at the price of an average bolt.
no chrome
