    Thinking about a project but I need to compare the muzzle outer diameters of a 10/22 and a Mk(?) with a standard tapered barrel. Problem is, I can't find anyone that has the pistol for comparison. Everyone here (including me) has the bull barrel.

    If memory serves, it's iddy biddy.

    Actually, I don't know (and never did). Maybe someone over at RimfireCentral.com can help.

    Not sure about what you want to know, but if it is the muzzle dia. of barrel ahead of sight band, it is as follows. Mk I made in 1956 with 6 in. barrel .500 to .502 Mk II made in 1999 with 4.75 in. barrel .497 to .498 Mk. II made in 2003 with 4.75 in. barrel .497 to .499 Hope this info helps, if not i can measure other dimensions.
