you can not cut a barrel, ever.
you can BUY a new barrel all the way down to like 6" for your 10/22 but you can never ever ever ever ever cut a barrel or have one cut.
(did i say ever?)
ever ever.
not even 1/2 of 1/4 of 1mm off.
ever.
prohibited firearm
(b) a firearm that is adapted from a rifle or shotgun, whether by sawing, cutting or any other alteration, and that, as so adapted,
(i) is less than 660 mm in length, or
(ii) is 660 mm or greater in length and has a barrel less than 457 mm in length,
(c) an automatic firearm, whether or not it has been altered to discharge only one projectile with one pressure of the trigger, or
(d) any firearm that is prescribed to be a prohibited firearm;
That's not true either.
Do not cut it shorter than 457mm for rimfire or manually operated firearms or 470mm for a semi automatic non rimfire.
Personally, I like leaving about 25mm extra because you know who is going to be measuring it if it ever does happen... They don't hire them for their math skills.
So 18"min barrel for a rimfire with a min oal of 26". But a "factory" made barrel can be shorter as long as the min oal is 26"
Cool thanks. Will I get tighter groups with a Dlask barrel? I don't know much about there stuff. Everywhere I look I see Kidd lol.
