Can I use a Vias Muzzle brake that was in my 6mm and install it on my 22/250. Bore hole measures .250
That's not a lot of clearance (7 thou) on the original rifle, everything including the carbon build up would want to be under control.
You wouldn't want to run that tight a clearance on a 90 degree ported brake.
I recommend 25-30 thou clearance on my brakes but they are angled back ported brakes not Radial like the Vias.
Even running over double that clearance has little/no affect on my brakes performance
Its going from 6mm to a .224 .Its has a bore diameter of .250 and will be used on a .224 diameter bore (My 22/250) Others have said it will work fine.
