I`ve been thinking of picking up a supressed .22 lately. I found two that I`m trying to decide between, a Ruger Mk2 with 6.5" integral supressor or a Bushmaster AR upper,converted to .22LR only with a permanently installed Ceiner kit and a 14" integral supressor (and 3 30rd. hi caps!). Both were built by a place called Tactical Solutions (anyone familiar with this outfit BTW?). I`m just wondering how many rounds I can put through something like this before the supressor wears out or needs to be rebuilt. I could see myself putting a LOT of rounds through that AR upper. Marcus
