Gunsmithing Browning thread pitch on A-bolt w/ BOSS??

[ChadTRG42]

Does anyone know the thread pitch on a Browning A-bolt with the BOSS-CR (conventional recoil) system? I'm wanting to take the CR off and get a muzzle protector or maybe install a brake. Browning tech support says "it's company policy to not release that information". They suck!
Thanks in advance!

The one I have seen is 9/16"-24 and that was on a 30-06, yours may be different.

Im sure the A-Bolt and the Model 70's w/boss used the same threads...but the 9/16"-24 threads 308MAUS3R was refereing to was on a model 70 w/boss....

Mine came with the CR tube not the boss. I wanted a brake on it so had one threaded to fit. I have been trying to find a boss brake for it for some time and have fallen short...

That's what I'm wanting to do. Mine has the CR. Does the BOSS and the CR have the same threading?

The BOSS Muzzle Brake and the BOSS CR have the same thread pattern (9/16x24) and can be switched back and forth as needed (only the .338WM and .375H&H have different threads to my knowledge)...the problem is finding the @#$%ing brakes for sale!!

Brownell's sells the CR units, but I have not seen brakes for sale separately except on auctions, eBay, etc.

Make sure the heavy barrel on your M-1000 isn't different than a standard barrel also.

I know you've got to have a micrometer and a thread pitch gauge around there.

Best to rethread when you have the brake in hand.
