Lancer Carbon-Fiber Shotgun Extension Tubes (LSX) are designed to attach to existing shotgun magazine tubes to provide added capacity to the shotgun.
Machined aluminum components combined with a lightweight carbon-fiber tube create a lightweight, durable extension to your shotgun.
An extra-long spring is included that can be cut to optimize loading.
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.
The LSX-5X adds five rounds to magazine's capacity.
