SWR, Gemtech, Norrell 10/22 integrally suppressed barrels
The Norrell 18" integrally suppressed 10/22 barrel is the "Mac Daddy" of 10/22 suppressors for easy disassembly. I have one on an original Norrell/Ruger 10/22 suppressed select fire smg and it is tops. This suppressor can with stand 7-8,000 rounds of dirty .22lr before dissassembly and cleaning per John Norrell. He sells a spanner wrench and threaded dissassembly tool with his suppressors that make taking them apart a snap - and I don't mean the kind of 'snap' that makes you go, "Oh, sh*t!".
Also have a SWR (Southeastern Weapon Repair)
http://www.swrmfg.com/main.htm 77/22 integrally suppressed barrel built by the owner, Joe Gaddinni, that is every bit as quiet as Gemtech's Quantum
http://www.gem-tech.com/ and AWC's
http://www.awcsystech.com/ best 77/22 integrally suppressed system - maybe a little bit quieter, in my humble opinion.
I have a couple of shooting partner's with a GT Quantum and an AWC. We have shot all of these suppressors side-by-side at the range to compare ............. that is really the only true test of the sound suppression and 'tone' and 'signature' of a suppressor.
Also have a Ruger MKI pistol with an integral suppressor by Ralph Smith of Red Dog Target Supply
http://www.rdts.com/ in Arizona. Great work, very quiet suppressor, and a nice suppressor for the money. He also builds integrally suppressed 10/22 and 77/22 barrels for a very reasonable price.
Mark Serbu builds some of the best and quietest 10/22 integrally suppressed units and is priced reasonably also. I have shot a few of his suppressed 10/22's and Ruger MKII pistols - very quiet and impressive.

In my opinion, I would stay away from Sound Technology/Mark White. While he is a nice guy, his suppressors have a different poi at different distances. Been there, done that, sold 'em.
That seems to be a mark of quality with 10/22, 77/22, and the MKII integral suppressors and screw on suppressors. The better ones don't change poi when shooting at different distances.
There are literally hundreds of c2 suppressor manufacturers out there and you're best bet is to shoot the model/brand you are most interested in and several more before buying to determine the best value for your money.
Good luck in your choice and a quiet 10/22'n to ya,
Clay
Pic is the SWR 77/22 'carbine' rifle. Very quiet unit with a 16" integrally suppressed barrel in brushed stainless.
