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.

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:

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!

: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.
