So why would I want a 9mm AR?
1: I can generally buy 50rds of FMJ 9mm for less than I pay for 40rds of Q3131A. Buying in bulk is at even greater savings. That means I can shoot more.
2: Sound suppression. Subsonic 9mm is cheap, easy to come by, and it will actually supress decently
You can suppress supersonic .223/5.56mm, but it's still on the loud side.
3: Colt 9mm parts are EXPENSIVE! Another manufacturer on the market would help make the prices more competitive.
4: I wouldn't have to buy it from Colt, who's politics suck. Colt doesn't give a crap about it's customers. Bushmaster seems to care about it's civilian customers.
