Feenix, the problem is that Browning chose to thread their rifles with abnormally short threads, unless you use a brake that you can grind/cut to index properly or have the barrel cut and rethreaded, you are stuck with using Browning's Recoil Hawg Muzzle Brake. There just isn't enough room for a locking collar to use a self indexing brake.
I couldn't find an aftermarket brake that I felt comfortable with how it installed, so I opted for 2 Recoil Hawg brakes. It works, but it is loud and hideous looking.
The MBM may work, the APA says thread length needs to be .625", so I wouldn't be able to use them.
The MBM appears to use both internal and external threads, it appears that the locking collar threads are external on the brake, I have never had a self indexing MBM brake, but later today I will call and verify.
