Have two test barrels approx.1-1/2" shank for 5" I think, gas port is 1-3/4" in on shank, has a straight cut reduction (no taper) remainder is 1-1/4" (as I said sizes are approximate. One is a .358 and is 26" total length, the other is .458 and is 27" long I believe. Think you could get either cut down to a 3" shank or pretty close and leave at a 1.25" straight contour or contour to what every preferred. Would have to dig them out to see if stamped with any info on twist if there is any if interested.
