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: 1/2×28 – 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 – Matte Black
