Applying our experience in carbin fiber product design and lightweight component development, Lancer has created the Lancer Carbon Fiber Shotgun Extension Tubes (LSX). Each LSX is designed to attach to existing shotgun magazine tubes to provide added capacity to the shotgun. We've combined precision machined aluminum components with an advanced carbon fiber tube to yield a lightweight, durable extension to your shotgun
