Had the same Wilson Combat barrel in 7mm-08 (short stroking), 18" SS match grade Tactical Hunter 1-9.5" twist, rifle length gas tube, .750 gas journal, carbine spring w/ 3.8oz. buffer. It came with a slightly smaller than .076" dia. gas port. Ran a #48 drill (.076) thru it to clean it out. Still would not lock open on last shot. Opened up to #44 drill (.086), now it functions perfectly with carbine spring and 5.4oz 2 1/2" buffer. I Don't see anything close to .090" wire gauge drills available, closest is .0935" which is a #42 drill, or .089" which is a #43 drill. This rifle runs perfectly now, - 3:00 o'clock, & 5.4oz buffer. Thanks for the confirming information on this Wilson Combat 18", UncleDano.
