akrietWinchester 70 B.O.S.S. system thread measurement
Does anyone happen to know what the threading measurement is on the Winchester 70 BOSS rifles that were made and discontinued a few year ago? Could it possibly be 5/8"x24?
All I could find was the thread size is different for the .338 Win Mag. as apposed to the other Calibers .
A Smith who has worked on them needs this question or you need a thread gauge so as to check it .

Toomany ToolsThe ones I have aren't installed. A friend had three or four still in the boxes and gave them to me for possible use as muzzle brakes.
