muzzle brake design I'm playing with

And while speaking of Brakes, check out this Hi-Speed photo showing the gas Jet dispersion through the ports on a Brake.

Have fun trying to machine the ports in that configuration without a sinker EDM.

IMHO the ports are too small, at the inside hole. You will have poor gas flow, and there will be sharp corners where the hole and ports intersect. Slots can be milled, and open the sides more for better flow.

That just goes to show what you get when you only read the first post and post your own comment. Also you don't know how big the ports are as the are very few dimension listed. As for the edm yeah I can run one of those too. Did so for ten years in a mold shop. Now if you would have read a little further down you would see where I said I was having a hard time modeling the slot geo correctly. They will be milled, they will be .1875 wide and 72 degrees. But who says I don't have access to a Charmiles?? Or a custom broach?? Now 14 of these ports should be more then enough.


And in thinking about this again I now know how to draw it correctly and will post a more accurate picture tonight.

Cool pic and give me something to think about.

here's the real version we are looking for

VERY NICE!!!

Sorry if I cam off rude. You are right I should have read the whole thing. I have to deal with drawings like this all day so I guess I just jumped the gun a bit. I keep getting drawings with a bunch of sharp corners and I have to call the engineer to explain it to them.

The new design looks good by the way. I wonder how the added mass will effect the barrel harmonics. If you are going to make your own maybe make it tunable like the Browning BOSS system.

I have to deal with engineers too. Did so for over twenty years. Now I design what I want to build and build it. My issue is I'm not an engineer and don't have the time to sit in front of a CAD program all day and truly learn it. For some dumb reason I was trying to put those radii cuts in there the hard way. When all I had to do was click on the corner and add a fillet of my desired radius. So fixed.
As for tuning we are going to tune the loads to the gun. But yeah you could make a adjustable sleeve to correct the groups.
And you didn't sound rude. You sounded like a machinist. Blunt. I'm the same way. And don't mind one bit.
BTW a bench top charmilles sinker is on the wish list. Maybe next years taxes.
Used ones are around $2500. With everyone going CNC these thing are worthless to most shops.

I am glad you did not take it in a negative way. I actually have a Mechanical Engineering degree and help run our family machine shop so I have seen both sides of it. I have been toying with making muzzle brakes but just haven't had the time to do the requires R&D to make a commercially viable brake. I have CNC lathe and 4th axis on one of our Fadals so I may just make one for my AR.

I will take 2 dingle arms can you please ship to my home thanks. now what in the heck is a dingle arm

Have you looked at whats on the market recently? If you wanna make a brake that's "commercially viable" just cut out something with no functional purpose, lots of sharp angles, serrations, and scary looking barbs on it(think satan's penis). Then slap the all important catch word on it. Something like "tactical", "black hawk", "delta", or "recon" should work well. Hell...Why not all four? The mall ninjas will beat a path to your door.

Yep the new Delta Black hawk recon tactical Muzzle brake also available in non tactical delta black hawk recon version.

And thats the point. All this conjecture on how well the design will work with no regard to the current marketing of the taciticool stuff.

It's need Spikes like Rob halford arm bands.

Sorry if someone already mentioned this but I can not see it in the image but is there vent holes on the bottom of the muzzle brake?


If there is you might want to redesign it without any holes on the bottom because of the cartridge for that rifle. There will be a lot of pressure that will blow up and back any dust, dirt, pieces of wood etc. if you are close to the ground. All the top muzzles brakes for high powered rifle cartridges have no holes on the bottom of the muzzle brake just for that reason.

Nope no holes in the bottom

I finished the brake today
