The Carlson's 04505 Magazine Extension transforms standard capacity shotguns into high-volume platforms for competitive shooting and tactical applications. This precision-engineered extension adds eight additional rounds to compatible Winchester and Browning semi-automatic shotguns.
What Makes This Different
