When cycling the action, bottom of the BCG is quite rough and creates a lot of friction when sliding over the hammer... The feeling is VERY rough and creates so much friction to the point of occasionally binding and stopping the bolt from going home under spring tension alone. After just a dozen or so cycles I can see a small amount of accumulated material on the bottom of the BCG that wore off from where it slides against the hammer.
Is this normal and will it wear in / smoothen out with time?
