ok so whats the deal with the "mini muscle break" and how well does it work? Im having a 280AI being built as we speak from benchmark barrels in a #4 contour on a left hand sako 75 and wanted a muscle brake but i think the mini is all that will fit that contour. I want to spot my hits more than reduce recoil. My barrel is 25" long so the muzzle diameter should be .666". so whats your take on this. your gun is awesome and i like the setup with the bipod and all. pretty much the exact setup i want.
