Help finding muzzle brake

I have Cooper Firearms rifle. Its threaded 1/2x28 pencil barrel very light weight type mountain gun. 6.5lb in 6.5 cm. While 6.5cm doesn't kick much the muzzle jump from it being so light is bad. Can't spot impacts. Barrel is .610 at thread. I can't find any brake tapered to that small, want radial type never shoot prone. Although if side port is all I can find would take it. Anyone know a company that custom makes one or that has any that small and in 1/2x28? My Google search had a couple come up. But the 2 no longer are custom making. They had some for sale but not that diameter. Called Cooper now own by different company and they said they would look around for one, but never got back to me.
Maybe you know this. Muzzle brakes get their performance from diameter, number of chambers, port angle, etc. I guess my point is when you drop down to a barrel diameter, 1 chamber radial brake, you don't get much braking function.

You might check Harrels's.
 
Oops, I didn't mean to stir outside his goal. That was my bad.
That's why I responded as such in #2. If the OP is willing to compromise, he has plenty of options. I have a variety of MBs since 2003 and radials are the least effective ones I ever owned. Like you, I had radials - Vais and Gentry Quiet brake (there is nothing quiet about it) on my .300 WMs and could not got rid of them fast enough. Unfortunately, I still have one Vais brake that with the rifle I bought used for the action.

We all know about your, let's call it dislike, for the Vias and Gentry. Except those who are loosing memory. I haven't quite reached that point yet. LOL

If y'all help coop2564 find his, maybe someone could tell me where to find mine. I lost it years ago……if I can find it, I'd love to sell it! 😉 memtb

Most of the Harrel brakes do not give any specs or threads. I guess I could call Monday. Also found a guy SAS that has some he says he customizes too.

Weird. Most of them have sizing clearly listed, but a few have nothing. Hmm.

As I noted in #2, a reputable GS can custom build it for you. If you go with SAS, you might as well send your rifle so he can blend it with your barrel so it does not show a break in the transition, as shown in the picture below.

ADDED:

You can consult with Nathan at MBM if his mini beast brake can be turned down to .610" safely. I this in 4-port on my 7MM SAUM. As with anything we can only advise, but you have the ultimate decision. Good luck!

If muzzle rise is the issue, I'd forget about a radial brake and look for a side discharge brake that has holes on the top. Top venting brakes can be very effective in eliminating/reducing muzzle rise.
 
I have m77 in .338wm with a vias style radial brake that someone put on the rifle. It is not a heavy barrel by animals. I have a idea that it probably going to be worthless, Just loud. Barrel not big enough for baffle style brake. Not paying $1200 to rebarrel.
