The Lancer LSX Shotgun Extension Tube in the +2 configuration for the Beretta 1301 Competition (Lancer Systems part no. LSX-2X-BR) adds two additional rounds of capacity to the factory magazine tube, installing in place of the factory tube cap for a genuine increased-capacity solution for competition, hunting, or home defense. Lancer Systems builds the LSX line from carbon fiber rather than traditional aluminum, giving the tube a smooth-feeding extension that adds considerably less swing weight to the muzzle end of the shotgun, a real advantage for 3-Gun and other fast-transition competition shooters running the 1301. This +2 model measures 6.3″ and includes an extra-long spring that can be cut to the exact length needed during installation, along with a precision-machined aluminum adapter nut for a secure fit.
