This Lancer Systems LSX Magazine Extension Tube Assembly allows shooters to increase the ammunition capacity of their shotgun for use in action shooting competitions such as 3 Gun, for home defense, or for hunting. The LSX combines machined aluminum hardware with an advanced carbon fiber tube to produce one of the lightest weight, most durable shotgun magazine extensions on the market. Installation is fast and simple, requiring no permanent modifications to the firearm. Each Lancer LSX assembly comes with a carbon fiber magazine tube, aluminum mounting nut, end cap and an extra-long magazine tube spring (must be trimmed to length).
In order to increase the capacity of your shotgun without having the tube extend past the muzzle, measure from the front of the shotgun's forend to the end of the muzzle. This figure will determine the maximum length of the extension tube to use. Use of the Lancer Magazine Extension Tube Barrel Clamp (Product # 915788) is recommended if increasing the capacity by more than 4 rounds.
