The SB-X barrel is compact and lightweight; the perfect replacement for the heavy factory barrel. The bore length of the SB-X barrel is 12.375” and with the permanently affixed shroud the overall length increases to a legal 16.625” barrel thus giving the shooter all the benefits of an SBR* with NO paperwork. The barrel is threaded and the shroud is hollow so any 1” or smaller diameter suppressor (threaded ½”x 28) is the perfect addition and will maintain a compact overall length. Add the SB-X to your factory Ruger® 10/22 Takedown® and make your rifle the perfect packing/prepping companion. - *Short Barreled Rifle - Specs: - Weight: 12oz - Overall Length 16.625 - Bore Length 12.375 - Inside Diameter: 1.1 - Twist: 1-16 - Threading: 1/2x28 - Barrel: 6061-T6 aluminum - Barrel Shank: Stainless Steel - Colors: Matte Black and Silver with a Matte Black Shroud - Includes an inert display suppressor & NOW LOCKING MECHANISM - Silver
