I'd trade you an unfired MGM blued .22 Hornet barrel for it. 21" length w/1-14" twist. Standard, not K chamber, D&T for standard T-C "4-hole" mount. Barrel has been mounted on my G-2 but never fired (not much varnint hunting opportunity around here, and the centerfire ranges are a long drive. RF is easier). I could email you a pic, but it wouldn't tell you much more than my description....
