I had originally thought I'd be making a reflex design can for my 300BLK silencer project. But Schuetzenman inspired me to go a different direction. It made a LOT more sense.

I decided to go with a QA/QD design muzzle brake that would allow me to move the silencer amongst my various 30 cal rifles. Please be forgiving on the drawing, I just did it tonight over the course of a few beers and it's very rough with no dimensions on it. I wanted to through the concept out there to see what ya'll think about the direction I'm going. I'd like to get some input from the folks here that are far smarter than I in these matters.

Below I've got two concepts. The main body will be a bit smaller than 1 inch O.D. with a 30* mating shoulder. (the O.D. at the top of the mating shoulder will be greater than one inch) The top design is apx. 3 inches long and will add apx. 2.5 inches to the barrel length. The first chamber is an internal expansion area with a 60* port out the top. This will act as a compensator to counter muzzle rise. Two chambers follow that vent gas out the sides.

The bottom design does away with the compensator chamber and shortens the length by almost an inch.

Oh, the threads. I'm thinking about doing two threads at 8tpi with about 1/3rd of an inch of threads.

So please bring on the ideas and critique.

Thanks
