0.86" OD Muzzle Brake

[FearlessMagpie]

I want to add a muzzle brake to my Bergara b14R. It's 1/12*28 threaded and the barrel diameter is 21.3mm.

Where can I buy a similar muzzle brake but in 0.86" ? All the MB I found available in Australia are in 0.92"


Thank you.

Do other peopl put brakes on rim fires ? What boot are you trying to tame?
