It was a matt finish and not polished. Maybe my fault, I assumed all nickle boron where polished finish.

Bought this for an AR I was building, chambered in .223. fit was very good with no issues. Lubed it up good before using and shot 50 rounds through it without any jams or malfunctions. Worth the money in my opinion.
Installed in a pistol build
Looks good against burnt bronze. Great function.
Reviews requests are a little to quick.
This is the second one of these I have bought for a rifle build. I have used this BCG in two day fighting rifle classes with both brass & steel cases. The BCG did not disappoint. With more then a few thousand rounds cycled, I have not had any issues. And yes, I do lube the bolt.
This bolt works great in my 556 build and looks great!!!
