Thread: Ar question

You can buy another upper, but not as large as .308, that will require a larger lower hence called the ar10

You could change uppers with calibres such as
9mm
300 wtf (whisper, blackout etc)
6.8
30 cal wilson tactical
.204
7.62x39, just to name a few
some of these calibres however will require specialised magazines aswell, and therein can lie reliability issues with mags not feeding
Most can be remedied however
