Die Free Co makes firearm grips and rifle-control accessories focused on ergonomics, best known for the Kung Fu Grip. A New Hampshire-based maker founded by a small team with backgrounds at Sig Sauer, Accuracy International, and Q, DFCO takes its name from the state's "Live Free or Die" motto and builds well-engineered AR-platform accessories. Its focus is the contact points between shooter and rifle, where small changes in geometry affect control, and its gear is used by competitive shooters, law enforcement, and defensive-minded civilians.

The lineup centers on rifle ergonomics for AR-platform rifles. The Kung Fu Grip is a reduced-angle AR pistol grip for AR15/M4 and AR10/SR25 platforms, the Kung Fu Grip Plug adds length and internal storage, and the Tiger Claw is an angled M-LOK foregrip that pairs with the grip.

What DFCO concentrates on is grip geometry. The Kung Fu Grip uses a reduced angle, roughly twelve degrees, that lines up the hand, wrist, and forearm more naturally than a traditional vertical grip, which eases tension on the wrist and discourages the white-knuckle gripping that creeps in over a long string of fire, while a finger groove sets a repeatable purchase. The Tiger Claw carries the same texture and finger-groove design to the support hand, working as a hand stop and index point for consistent positioning and recoil control, and the Plug extends the grip for larger hands while holding spare batteries or small items. Because these parts sit where the shooter actually touches the rifle, they have an outsized effect on comfort and repeatable control.

Pair a grip with an optic and a weapon light, and compare other control accessories in grips.
