What's in the Box Die Free Kung Fu Grip & Set Screw Complimentary DFCO Sticker Contrary to popular belief, not everybody was Kung Fu fighting. But you're with DFCO, so we know you get down. The Kung Fu Grip from Die Free Co was design for AR15/M4 & AR10/SR25 platforms*. The reduced angle of the Kung Fu Grip provides a natural fighting posture, especially when fired from modern standing and prone positions. Comfort is vastly improved when installed on firearms with a shorter length of pull (LOP), but it also feels right at home on all other firearms with a standard length of pull. The average person's hand, wrist and forearm are in line with one another with the 12 angle of the Kung Fu Grip. This alleviates tension under the ulnar nerve, and increases freedom of movement of the hand and fingers of the shooter in comparison to other grips. The enhanced finger groove allows for a repeatable purchase on the grup, and further reduces hand fatigue by discouraging the shooter from white knuckle gripping. * NOTE : While compatible with the above mentioned platforms, some configurations may leave an aesthetic gap between the grip tang and receiver. This will not affect the function or reliability of the Kung Fu Grip, or the platform it's installed on.
