might wanna check the laws first. It is illegal to make a pistol out of an action that is designated as a rifle action. Pistol meaning a barrel shorter than 16" and/or a total gun length of less than 26".
However, as long as the barrel is atleast 16" AND the total length of the firearm is 26", it is still considered a rifle.
Someone please correct or add to if i am wrong, but i am almost positive this is what it is.
What i thought about doing to mine was to take my Choate ultimate varmint stock and cut the butt end of the stock off just after the pistol grip, then just smooth it out. I have an 18" barrel on a short action Savage and it just makes the 26" limit.
