Nordic +3 Mxt Kit 12ga Bk Needs Nut

The Nordic Components +3 Magazine Extension Tube Kit for 12-gauge shotguns is a drop-in extension system designed to add three rounds of magazine capacity to compatible 12ga shotguns. This upgrade is essential for users running magazine-fed shotgun platforms who require increased round count without switching to a different firearm platform. It is particularly useful in scenarios where a higher ammunition capacity is critical.

Constructed from anodized 6061 aluminum, the kit provides weight savings and corrosion resistance, making it suitable for extended duty cycles. It includes a full-length spring that maintains consistent feeding pressure across the extended tube, ensuring reliability under rapid-fire conditions and with varied ammunition types. The dimensions of 6.25 x 1 x 14 inches and a weight of 0.38 lbs reflect a purpose-built profile optimized for standard 12-gauge magazine systems.

Operators and shooters running self-defense or tactical shotgun platforms benefit from this capacity increase during training courses, competition phases, or duty deployment where reload frequency directly impacts performance. The extension tube kit is compatible with the Nordic Components extension tube nut, creating a sealed, durable assembly that tolerates harsh environments. This kit is ideal for those looking to enhance their existing magazine capacity without the need for complete replacement magazines.
