This is a multi caliber setup to used inside of any D-Cell metal tube. Aluminum, Stainless Steel or Titanium.
Outside Diameter of 1.50 inside Diameter of 1.35+/- .02
I.D. doesn't really matter since you will need to scale baffles anyway.
This has been tested on 556 on 11.5 inch barrel supersonics, and 556 subs. Others have tested with the Overbore on 300BO subs with no issues.
PCC should hold up fine since 556 is the higher pressure of the two. 308 has not been tested.
