Finally!

[Matt.Cross]

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.

congrats....

[Rsquared]

Well it's about time. <laughs>

 

Just kidding. I know all too well about BATFE timeline.

Cool brother. <thumbsup>

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:

Sheeeeit - you got it!!!  <thumbsup>

*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!

Damn Murphy!!!

[Rsquared]

Damn Murphy!!!

 

Yeah.....him and I go waaaayyyyy back.

[Matt.Cross]

Yeah.....him and I go waaaayyyyy back.

 

 

This made me laugh out loud for quite some time. Thanks for making me feel better. 

[Matt.Cross]

It's together! The beast is finished and will see it's inaugural test firing tomorrow afternoon! I took some pics of the process too, gonna try and get them uploaded to update the thread.

: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.

Great job brother Matt. looks great. <thumbsup>

[edgecrusher]

Now where's the range report with video and shhhh  sound?

[Rsquared]

Outstanding machining there Matt. It'll be interesting to hear back from you on how it runs.

[Matt.Cross]

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

 

 

[Rsquared]

Yep........that's how they sound.

[unforgiven]

Indiana just allowed suppressors for hunting. :banana:

[98Z5V]

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.

[Rsquared]

Ding! Correct sir.

[Matt.Cross]

Unless you're shooting subsonic rounds...  At that point, all you hear is the action cycling.  No supersonic crack.

 

That's the next project, finding subsonic rounds that will actually cycle the action..... Lots of R & D to be done on that front!

[EasyEJL]

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
