Matt.Cross Posted May 3, 2013 Report Share Posted May 3, 2013 I'm going to the machine shop tomorrow to cut the taper attachment for my barrel so I can attach my suppressor. This has been a long time coming, and I'm really excited. Keep your fingers crossed that I get the part right on the first go. If it all goes well, I'll be updating my suppressor timeline thread with some range pics/video. Quote Link to comment Share on other sites More sharing options...

98Z5V Posted May 4, 2013 Report Share Posted May 4, 2013 Taper, taper, taper, Matt - hit that angle right, so the OPS can lines up concentrically. <thumbsup> Quote Link to comment Share on other sites More sharing options...
Matt.Cross Posted May 4, 2013 Author Report Share Posted May 4, 2013 (edited) Taper, taper, taper, Matt - hit that angle right, so the OPS can lines up concentrically. <thumbsup> You're right on brother, 20 degree taper and a minimum rear shoulder height of .920. The collar is going to be .936 so that my gas block will still slip over it with it in place, has a female 45 degree chamfer in the rear to match the profile of the front of the gas block shoulder. Overall length is 1.066 and on the front is the 20 degree gas seal taper coming rearward. Here's the drawing that Daniel Dregne sent me: Edited May 4, 2013 by Matt.Cross Quote Link to comment Share on other sites More sharing options...

Matt.Cross Posted May 4, 2013 Author Report Share Posted May 4, 2013 *insert 45 minutes of purple faced cursing here* It just simply didn't happen today. I got to the shop ready to do my bit, and the whole thing fell apart piece by piece, and ended up with the machines being needed for work more pressing than mine. So, it looks like I'm going to be making attempt #2 at this project next weekend. Dammit all! Quote Link to comment Share on other sites More sharing options...

Matt.Cross Posted May 12, 2013 Author Report Share Posted May 12, 2013 :wwop: Had to do it bro. :hethan: Well, if you're gonna twist my arm... We start with a center drilled piece of 316SS bar stock.. Step drill it up a little... Bore it out to .800" with boring bar... Now cut OD to .936" to match gas block.... Cut 20 degree angle at front per drawing... I don't have any pictures of cutting the 45 degree chamfer in the rear, but it was very simple, and finally pictures of the finished product.

Matt.Cross Posted May 15, 2013 Author Report Share Posted May 15, 2013 Now where's the range report with video and shhhh sound? Working hard on that bro, but I imagine it will sound almost exactly like Quote Link to comment Share on other sites More sharing options...

98Z5V Posted May 16, 2013 Report Share Posted May 16, 2013 Yep........that's how they sound. Unless you're shooting subsonic rounds... At that point, all you hear is the action cycling. No supersonic crack. Quote Link to comment Share on other sites More sharing options...

That's the next project, finding subsonic rounds that will actually cycle the action..... Lots of R & D to be done on that front! Quote Link to comment Share on other sites More sharing options...
EasyEJL Posted May 16, 2013 Report Share Posted May 16, 2013 yeah, thats why i'm saving bothering with a supressor till I build a 300 AAC or .45acp AR. way more fun to go totally silent :) puff puff puff Quote Link to comment Share on other sites More sharing options...
