Noveske bcg question?

[george_995]

Does Noveske bolt carrier groups have any roll marks? Considering trading for a noveske n4 upper, I wanted to make sure parts are what advertised. The upper is from a factory rifle. THanks guys. <thumbsup>

Some carriers are marked with the "N," and some are unmarked.  The bolt will be marked "MP," sideways.
