I guess I'll do a step by step integral silencer build. Ive got 3 in the works but this is the first of the batch. I wont have the gun for a few weeks and the baffles havent shipped yet either. Using a 2000 ish Vintage Ruger Stainless Mark II Competition .22 Lr. I will be cutting the barrel back to 3 inches and using a non rotating silencer tube with titanium baffles from quiet bore. The tube I am using is 304 SS 1" OD mill finish 0.065" wall cut to 7 3/4" length. I trued it up in a lathe and broached the tube for a 1/8" key . I will not be threading the back of the tube but will instead solder ( or weld ) in a plug that I will use to tighten the tube up to the receiver and tension the barrel. The baffle stack will go in after that. Anyway first step. The tube is nominal .870" ID which is more like .872" so a 7/8" Dumont broach will fit after getting pressed in. Then the broach cutter pushes through and cuts a slot for a key. I will be using a woodruff key cut into the rear of the barrel. It wil;l become more evident what I am doing once the gun arrives. Heres a mockup of the broach cutter but it does go all the way to the tube. And the completed 1/8" broad after knocking the plug out. It was tight. I'll post more segments as parts come in.
