Kriss USA MagEx Kit 2 45 ACP Black 30 Round

The Kriss MagEx Kit 2 extends your factory Glock 21 magazines from standard 13-round capacity to 30 rounds total. Built for the Kriss Vector and magazine-fed pistol caliber carbines, this kit delivers serious capacity gains without compromising reliability.

Inclusion of durable reinforced composite materials keeps weight minimal while maintaining structural integrity under heavy use. The extended baseplate, outer sleeve, and matched spring work as a unified system, engineering-tested to function smoothly across repeated charge and fire cycles. This is a practical upgrade path for shooters running Glock-pattern magazines in their Kriss platforms.

Do not use with 10-round reduced capacity magazines; this kit is engineered specifically for standard-capacity G21 platforms.
