No you can't put a slidefire on without modification and a trigger job from what I hear. Friend has the s&w ar15-22 and if you plan on shooting a lot I suggest you get it. I myself have put 2000 rounds through his haha. Tacticooled it out with DE/black grips grips and rail covers, light, and an eotech. I may get my own and slap a suppressor on it.
