LANCER 738435616212 Shotgun Extension Clamp

Shotgun Extension Clamp - One Rail. Shotgun Extension Clamp with one Picatinny rail for use with the LSX Shotgun Extension Tube. The two aluminum clamping halves have high temperature silicone foam pads to ensure a slip free connection with the carbon-fiber tube and shotgun barrel. The clamping halves are held together with steel cap head screws and can be orientated so the Picatinny rail can be used on either side. Extension clamps are recommended for extension tubes that extend beyond the end of the barrel. They are also recommended for Remington applications due to the shallow threading on the Remington magazine tubes.
