althougth most claim to be "milspec", I feel that I might just get a complete Armalite or bushmaster, etc...
BUT, I was wondering if I get a top end like the P.O.F. gas piston upper, and decide I want a lower from one of the A,B,C,D,S,RRA, etc....than what would you suggest? I have heard and seen lowers that a have a very tight mag well, which I don't want. I want my mags to drop free for quick mag changes for three gun, yet feed/ seat well to facilitate reliable functioning in combination with the top end.
I only have experience with armalite and colt.
