I received a 20" A2 upper from RRA and it went together with no problem on a RRA lower. The last 4 RRA uppers that I mated with RRA lowers all need to be pressure fit to go together. Is RRA filing down the rear lug to alleviate some of the problems many of us had putting the two together? I am not complaining, I was just suprised at how easily the went together. Has anyone else noticed this?
