Okay, now I have to ask about feed ramps.
I'm researching barrels for what will be my first AR. (Many of you have already offered a lot of help in my twist rate question and thanks.)
I keep seeing that all of these 20" A2 barrels have "M4 Feed ramps," and those feed ramps were modified to increase reliability on the shorter barrels. I've also read that the M4 upper receivers have a matching profile.
Of course, I'm trying to build an A2 rifle. (I never do "easy," "common," or "simple.")
Can I just put one of these A2 barrels with M4 feed ramp onto an A2 upper receiver, or do I need to be searching for a 20" barrel with an A2 feed ramp? (Which I probably won't find-A2 anything is hard to find.)
