Just to confirm, the only two barrel lenghts that the Saiga 20 is made in is 19" and 22" right? I only ask because I want to know how much to cut off. I am doing the US parts conversion for a pistol grip and thought I might as well shorten it to legal limit.
The minimum barrel length for a shot gun is 18" right?
The barrel length is measure from the face of the locked bolt to the end of the barrel.
Minimum lengths per federal law,
Shotguns= 18" barrel,26" overall
Rifle= 16" barrel,26" overall
