muzzle brake design I'm playing with

[kcstott]

This will be for a Rem 700 in .300 Winmag

Going to make a first article this weekend

Done here it is

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.

Nice! You using inventor?

[CSACANNONEER]

I like it. If it works well, I'd be interested in one for my 700 in .308.

what is that?? never mind looked it up. Nope that's Alibre CAD.

CSA it'll work that i'm confident of. just will it look good. Because 99% of this stuff is looks not function. KDF brakes work better then anyones but they look generic


No ribs



All ribs

Over all dimensions are 5" long 1.125 diameter tapering down to .950" for a bull barrel 5/8"-24 threaded. reamed .350

Partial ribs looks best IMHO

Yeah I was feeling that way too.

[CSACANNONEER]

Yea, partial ribs or plain look the best to me. I am shopping for one and do like the looks of yours. So, if you want to sell one, I'd be interested in trying it out. I do know that different brakes do affect the precision of a firearm too. So, I do want something that won't make a sub moa shooter into a 4moa shooter or, even a 1.5 moa shooter.

Accuracy wise I have no clue as i have no idea what would make it less accurate.

Curious what your plans are for making the pie cut vents.

Looks heavy and there is not enough area in the vents to an effective brake.

The way the venting gases influence the bullet? I really don't know either but, I do know some highly respected extreme long range shooters who have gone through dozens of custom made brakes for 50BMGs trying to get the most out of their rifles.

Milling machine and some expensive tools I haven't figured out how to draw a rotational cut with a radiused internal edge. So those slots you see will have a .093 radius top and bottom. I'd need an EDM to cut them square as pictured. It is going to be heavy thats for sure. My cad software says 3.3752 cubic inches so nearly one pound. This was a design my uncle came up with and it's not meant for a door kicker.

How about flutes lengthwise?

The weight alone will reduce the felt recoil.

I'd just drill a hole in the center and then plunge an end mill down at an angle to make the vents.

What are you using for CAM?

Does Alibre not have a radius feature? Lofted cut? There are a couple others ways to make the feature other than a rotational cut.

It does I just need to figure out how to do it. I did us the lofting feature to get the taper from 950" to 1.125"
It's probably one of those instances where the order of features needs to be changed to do what I want it to do. I'm sure it can be done I just don't get the chance to play with the software as much as i'd like.

Not really concerned about weight it's going on a 15 pound rifle so weight is kind of a moot point

The design is based on the the FN tac rifle that was written up in some gun rag. My uncle in Ohio wants a copy of the brake for his rem 700 so there won't be any lateral fluting sorry

[USPSA GM]

Just out of curiosity could you break down the design features that will make this work and are we talking about reducing recoil or muzzle flip? Or both?

I have had the chance to work with some of the top pistol and rifle smiths over the last 20 years and have gone thru probably close to 20 different comp designs of the years and I am still looking for something better. Always willing to learn something new.
