Designed by Magpul as a replacement for the standard AR-15/ M-16 pistol grip, the Magpul MIAD GEN 1.1 Grip Kit (Type 1) is specially engineered to help your weapon fit better in your hand and improve weapon grip comfort, function, and accuracy. With removable and replaceable front and rear panels, this grip kit guarantees a custom fit for each hand. The interchangeable front and rear straps also allow you to change the grip for different hand sizes or for different mission requirements. The optional storage cores mean you can stow batteries or a spare bolt/pin firing, for an even wider range of use.
