I just saw a special on New Frontier Armory’s site for side-charging AR uppers, which apparently are made by Gibbz so they should be good quality. One offering is in 10mm, so I was wondering if anyone here has one in 4” or 8” and what you thought of it? I’m toying with the idea of a 10mm upper, but I already have a stash of 45 ACP ammo and none in 10mm, so my thinking is, “Why go with 10mm and have to buy ammo, when I already have plenty of 45 ACP ammo?”
Reloading is NOT an option. Factory ammo it is.
