How Does the KRISS Mag-Ex2 Work?
KRISS has two different Mag-Ex2 offerings: the DIY Mag-Ex Kit 2 and the Mag Ex2 Extended Magazine. The Mag-Ex Kit 2 is an extending base plate for factory standard Glock magazines. It is made up of the extended baseplate, outer sleeve, and extended spring. KRISS constructed the Mag-Ex Kit 2 out of durable and lightweight reinforced composites.
The Mag-Ex2 Extended Magazine is a simply fully assembled Mag-Ex Kit 2 with a factory standard Glock Magazine.
Combining the Mag-Ex Kit 2 with the factory standard Glock magazine body and follower allows for reliable feeding on the KRISS Vector, aforementioned Glock handguns, or any Glock magazine-compatible pistol caliber carbine.
The Kit retails for $35.95 while the Extended Magazine retails for $66.95. For more information, please visit KRISS-USA.com.
