Barrel is 9".300blk and the gas block is superlative arms. The problem is the instructions for the sa block say to space the gb .025" from gb shoulder and the shoulder on the ba barrel has a slight bevel to it preventing me from accurately spacing the gb with a feeler gage. Is the bevel there to represent the correct spacing when butting the block against the shoulder since its not at 45°?
