IT's cool to have a .22 upper and all, but really, is it neccessary? I mean, I bought an AR cause it's a relativley high powered rifle.

If I wanna shoot .22, i'd just bust out one of my Rugers.

I guess you wanna look cooler than all the others while shooting at the USOC, then hell, get one!!

That being said, do you guys prefer dedicated uppers, or do the CMMG conversions work just as well.
