    rifle barrel length question

    I recently bought a fresh Mosin nagant, and decided to retire the old one. ($20 rifle, with a screwed up feed, damaged sights, non existant blueing, and furniture that looks like it has been attacked by an angry beaver )
    Instead of turning it into spare parts, I had one of those off the wall ideas, that requires some knoweldge of the law I don't currently posess.

    First the idea

    The bayonet mount is welded to the barrel approx 3 1/2 inches from the end of the barrel.

    I would like to shorten the barrel to either the minimum legal length, or at least just before the bayonet mount.

    I need to know what the minimum legal length is, and how it is measured. (i.e. from back of the bolt/opening in the receiver/ro what???/ to the end of the barrel.

    Also entertaining the thought of cutting the stock down to, or else making, a pistol grip and mounting an old scope on it.

    I really don't plan on shooting it,(I like my wrists just the way they are thank you very much) but it will definately make an interesting conversation piece.


    Sooo, anyone know what the law is, and how to measure it?

    Bryan - I think best bet might be to go browse the ATF site.

    I reckon anyways you can shorten barrel down to 16", so it'd be a carbine. Measure from closed bolt face to muzzle if I recall correctly.

    But re the stock changes well - you will have to maintain IIRC an overall length end to end. Once it gets too short you may be into trouble.

    Class3NH, rfurtcamp etc are more qualified than me to comment on this.

    The barrel has to be a minimum of 16". Overall length has to be at least 28". That is the current federal law.

    Thank you P95 & ACP!

    Do you measure the 16" (actually 16.5 just to be unquestionably on the safe side of the law) from the face of the bolt?

    Or is it 16" from where the chamber becomes the barrel?

    Bryan - again subject to other's confirmation - with a ''one piece'' barrel, the length is IIRC taken from chamber rear/breech face - to muzzle.

    I think it will only be revo's where barrel itself is measured not to include the chamber, because separated.

    For not mistaking the measurement:

    Close the bolt.

    Insert a cleaning rod into the barrel until it hits the breech face. Mark it with tape at the end of the barrel.

    Take it out, measure it, and subtract (math, ewww) the length that will put it to 16.5". This is how much you can cut off.

    There are some nice stocks out there for the Mosins. Check out Boyds for some nice furniture, and there are some synthetics out there.

    Basically, that is how the BATFE does it, but you don't subtract anything, the measurement is from the bolt face.
