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.
The LSX-4X adds four rounds to magazine's capacity.
