Where did you get the break on yours? How much was it installed? If you don't mind me asking?
I usually send them to:
http://www.muzzlebrakes.comLately, if Benchmark in Arlington can get to it quick enough I have them put a Vais or Vais style brake on for me.
The going rate is around 200.00 that includes the brake and installation. You can call Harrell's and purchase a brake in the raw(25.00) and pay a smith a 100.00 bucks or so to install it. They work well, especially for the .284 bore diameter.
I did notice Muzzlebrakes.com did raise their prices a bit.
