I would be careful with the 22 adaptor kits. The .224 bore with the 1-9 or faster twists have been known to not stabilize .22lr the best. Make sure it isn't keyholing before using the can.
I run a 22 conversion and can on my 7 1/2" SBR and love it! So far it has ran great with good accuracy. Yes, it is a little dirtier than centerfire but nothing a normal cleaning won't take care of. Enjoy it
At a class in TX I borrowed a buddies GEMTECH and put it on my TacSol upper. At first I wasn't really all that impressed, it sounded a bit loud. When I had my buddy shoot it I was standing about 8 feet to his four o'clock and the bullets thwacking into the muddy berm were louder than the report. I was hearing the conversion kit cycling through the CavArms receiver/stock.
Hearing it from an observers perspective gave me wood.
A buddy and I have been doing this for years. Tens of thousands of rounds...multiple worn out components on the kits...and very very few problems that could not be chalked up to cheap ammo or worn out springs.
We both shoot suppressed constantly, and the only baffle strike either of us has had was attributed to a bad round, which is bound to happen when you shoot as much .22lr as we have. I have had four dedicated rimfire suppressors if that tells you how much I like rimfire shooting.
