I keep bugging Olyeller with these questions, thought I better try on here
Anyways...I'm wanting to replace an A2 upper with an flat top style...like the total dumbass newb that I am , I went ahead and bought one without knowing about the feed ramp difference...well, needless to say, mine has the standard cuts...the new upper has M4 cuts....so my question is.....can I replace the barrel extension without replacing the barrel??
