As long as the thread is 1/2-28 thread. Then you can mount it on any 22. The Smith & Wesson M&P15-22 comes with a standard 1/2-28 thread. tacticool makes adapters if needed, but as long as your came with a flash suppressor then you shouldn't even have to futz with it

Frank, yes Sir you can. The MP 15-22 has 1/2-28 Threads so this is a direct attachment suppressor. Cheers and stay safe!

Frank, Absolutely. Take the flash hider off and this silencer will screw right on.
