muzzle brake design I'm playing with

The Finished Muzzle Brake

Not is it only esthetically Gorgeous. But with the applied physics, And math and design changes we made together. It will also have the functional result of not only shaving the recoil of an extreme load for an extreme distance but will help with acceleration to get it there. LOL The math does not lie. Which is about 2.8 to 3.1 mach leaving the end of the muzzle and which can accelerate slightly more for a quick moment. Keeping it supersonic and stable depending on the load that we find works the best for accuracy and distance.

I know I will be laughing the first round I put down range when we put it to the live Test

AWESOME work KC

Ok two new designes
.750" -.950" Diameter taper, 2.75" long scaled for an AR15

This one just has traditional vertical slots


And this one is a scaled down version of the original design.

Hey, I've got an idea about brakes coming from an engineers head, one of the problems with bakes is getting your exit bore to be concentric to the barrel. Why haven't high precision target shooters, that want to use brakes, adopted a taper mounting instead of a traditional thread-on mounting? If you were to create your barrel and brake to mount using something like a #1 Morse taper, with a threaded locking ring to hold it down, you are now getting an extremely accurate mounting.

Obviously this would be a very custom system, but if somebody is building a $5k rifle anyway, why not?

The only advantage a tapper adds is a more rigid mount in relation to holding the two axis in alignment due to radial loading

Personally I've never run into a issue of concentricity errors. Now that may be the case with production guns but not on stuff I've machined.

When threading a barrel I indicate the bore and cut my threads off that. Then cutting a square shoulder on the threaded tennon to butt up against. I cut the brakes by drilling reaming and threading in one set up.
This insures the least amount of axial and concentric run out.

The issue I have seen is when someone uses a die to thread a barrel. To me that is an ametuer at work. All barrel threads should be cut on a lathe using the single point method.
