After two years of hemming and hawing over a silencer design, waiting 11 months for ATF approval and another year of waffling over baffle design, I finally built and tested another 50 caliber rifle silencer. This one is for an LAR Grizzly 50 BMG rifle, my previous design was for a much smaller 510 whisper.

It doesn't hurt my ears to shoot in the open without protection, but I'll use ears plugs when I shoot it in the future.

Very well done, if I may say so! Nice machine work.

First attempt at cutting threads, tap got stuck and I had to cut the piece off of it.


I ruined 5 inserts getting the threads right.


Completed threads. The unthreaded area mates against the barrel in back of the threads.


The piece on top mates with the threaded area in front of the barrel threads and on the muzzle.


Completed rear end cap.


60 degree step cone baffle and spacer. Baffle is about .010”, spacer is about .060” thick.


I used a piece of scrap 2” tubing as a welding jig. I tacked the spacer and baffle together through the hole, then welded it while it was pressed tightly between centers in the lathe.


Baffle press fit between spacer prior to tacking.


The lower drawing is the approximate design used. The last baffle is actually a flat baffle with a slight cone in the center.


Assembled silencer prior to welding/painting.


Done.

There were some complaints about the sound quality so I re-edited the video hopefully with higher volume.
