EXmatch™ Barrel Contours

All dimensions listed will remain the same regardless of barrel length. For prefits or contoured blanks, the only aspect of a contour that changes with barrel length variations will be the length between C and E. Also, the angle of the contour taper (if any) from C to E will change depending on barrel length.

The muzzle diameter (E) is measured on a contoured barrel or blank and does not account for any muzzle threading. Threading a muzzle will cut a shoulder (typically) .625" back from the normal muzzle end and that shoulder (at the end of the threading) will be a slightly larger diameter than what is measured at E (except for on contour #12). Take this into account when selecting a contour that will have a threaded muzzle.

In some instances, the gas block journal length (D) will be 1" long on contours where it would otherwise normally be 1.92" long. This can be due to overall barrel length, as typically extremely short barrels will have the 1" long GB journal instead of the 1.92".
