Nordic +1 Mxt Kit 12ga Bk Needs Nut

The Nordic +1 MXT Kit 12ga Black is a magazine extension tube assembly designed to increase capacity on compatible 12-gauge shotgun platforms. This extension tube kit adds one additional round to your existing magazine system when used in conjunction with the appropriate extension tube nut, making it an ideal upgrade for operators seeking incremental capacity gains without a complete magazine redesign.

The kit features anodized 6061 aluminum construction, which provides corrosion resistance and weight efficiency—critical for duty weapons exposed to varied environmental conditions. The integral cap design simplifies installation and maintenance, while the full-length spring ensures consistent feeding and reliable magazine function across varying ammunition types and shot shell configurations. The compact dimensions (4.25 x 1.25 x 14 inches) maintain ergonomic handling characteristics while delivering measurable capacity improvement without significant bulk addition.

This extension is suited for law enforcement patrol officers, tactical team members, and shotgun enthusiasts prioritizing incremental capacity increases. The +1 configuration is particularly valuable for operators running shorter extension tubes or those wanting modest tube modifications before committing to full-length tube replacements. Proper installation requires the matching Nordic Components extension tube nut—verify your existing magazine assembly compatibility before ordering to ensure seamless integration with your current setup.

Nordic Components' magazine systems are recognized for precision machining and consistent performance in duty and training environments. This extension kit represents a straightforward upgrade path for users seeking capacity gains through proven aluminum construction and minimal platform modifications.
