This was a huge game changer.... - CMMG, Inc Barrel Sub-Assemblyy, 22LR, 16in

If you plan on using using a super safety for 22lr dont mess around. Do t mess with the short barrels they don't have enough back pressure and they're super difficult to mag dump.this barrel changed everything now it's rediculously reliable will mag dump even the oldest cheapest ammo.allthough the nitride is annoying to drill, ended up messing up my FSB and had to just weld it onto the barrel, but I did make it look really clean. And Because it was such a night and day difference I think I wanna buy another barrel and make a second upper. I feel like I won the lottery.
