View Full Version : Suppressor Design and Theory

January 30, 2009, 19:55
Well, I am about to buy a new lathe and i would like to make a few cans (with of course the appropriate paperwork and tribute paid to the feds). BUT, I was wondering if there is any way to find any functional designs or even better yet any blueprints. Any direction here would be helpful. I do have the plans for the oldschool ingram MAC supressor but I was looking for other ideas.

I will most likely start with a 22, but I would like to build one for an AR I want to SBR just for kicks. Yeah, I know they are relatively inexpensive, I just like to make stuff myself when I can.

If I were you I would start by gathering up all issues of Small Arms Review which discuss suppressors. When you have read everything they discuss in there you may have some understanding to start from.

One problem for you is the amount of trial and error which the best makers have to put into baffle geometry to tailor a can for one specific caliber. Another problem is the toughness of the materials they are working with.

The fine points of current suppressor design are tightly held company secrets - this is mostly because the difference in the last 5 to 10 dB drop (a night-and-day difference in performance) is accomplished by small changes in dimensions which cannot be adequately explained well enough to cover with a patent.

You Should pick up both of Al Paulson's books on Silencers

the Book of Patents by Neil Parker

I found Al Paulson's books to be a review of existing silencers. It barely scratched the surface on theory. It had no equasions or even rules of thumb on manufacture of new designs.

If I had to purchase again, I'd get the silencer patent's book. Paulson's is fluff.

or do your own research

Thanks for the input guys. I just registered over at silencertalk so i will be spending some time there for a little while. Thanks again

silencer talk is the way to go...great diagrams

I am thinking of trying two different styles...Teh monolithic core and then a K baffle.

Teh mono baffle seems to be a very simple lathe and mill project
