A friend told me about a 6.5-284 Savage barrel w/ a factory muzzle brake. This is the style of brake that can be turned on and off. I am interested in finding out what configuration these were made in.
Are these:
sporter or varmint weight?
S/S or Cro Moly?
Length?
small shank or large?
9" or 8" twist?


I have only seen this style barrel/brake in a short (20" I think) 300 WM barrel in CroMoly
