Compensator for Model 10 18" Heavy Barrel

[Jakemore71]

Anyone know diameter off hand for my heavy 18" barrel? Looking at JP Enterprises compensator and was thinking the 5/8-24 compensator possibly wouldn't sit flush with heavy barrel.

Depends which "heavy" barre, Il think the FPs are considered medium heavy contour.
Several other factory Heavy contours out there as well.

I went with JP's larger compensator. It tapers down to the barrel at .875. A little larger then my barrel. JP Enterprises recommends it that way with the option of machining it to contour of barrel down the line.
