Okay shut your bitch ass up and pay attention.
The retro AR-15s are functionally fine - they can take any 5.56 AR mag. You're dumb for thinking they can't and probably shouldn't own a gun in the first place.
The real problem comes with the retarded purists and competition shooters behind them locking you into the 1:12 twist rate that restricts you to shitass 55gr plinking ammunition, especially in the midget model. That's fucking stupid, terrible for accuracy, and why we switched to 1:7 for heavier bullets that we never actually switched to because we can't have nice things and is the new standard. 1:9 is better but fuck perfection you get what you're told to want.
The AR-10s are made to use shitty aluminum mags with shitty flimsy feedlips because of the original magwell design, because fuck your wallet and buy my magazines.
Also enjoy those shitty three-prong flash-hiders that fall apart when you look at them, you faggot.
