Die Free Co Dos Boot Magazine Extension Black 5.56 +2 (10 x 3-Pack Carton)

The Die Free Co Dos Boot is a magazine base extension for Magpul PMAG GEN M3 magazines in 5.56x45mm NATO. It replaces the base plate and adds two rounds of capacity, with a broader contact surface that can serve as a monopod and an aggressive tread for handling. The Black, matte finish matches standard PMAG colors.

This bundle is a display carton of ten Black Dos Boot 3-packs, for 30 extensions in total. It is intended for buyers who need multiple identical components, such as dealers, training groups, or high-volume users standardizing their magazines.

Die Free Co specifies compatibility with 10-, 20-, 30-, and 40-round GEN M3 PMAGs. Confirm the carton contents and part number before ordering.
