The Lyman Plus 3 Magazine Extension For Winchester SXP Black Aluminum is a purpose-built upgrade that increases the on-board capacity of compatible Winchester SXP 12 gauge shotguns. Machined from durable black aluminum, this extension is designed to thread onto the existing magazine tube and provide a clean, low-profile look that complements the pump-action platform.

By adding room for three additional shells, this extension is well suited for extended range sessions, training days, or field use where extra capacity is beneficial. Its straightforward installation and model-specific fit help shooters spend more time shooting and less time reloading. The design reflects Lyman’s long-standing reputation for practical, shooter-focused accessories and consistent quality.
