FAB Defense AG-43 Tactical Ergonomic Polymer Pistol Grip with Finger Grooves - Black Finish for AR-15/M16/M4

The FAB Defense AG-43 tactical ergonomic polymer pistol grip delivers a secure, high hold on your AR-15, M16, or M4 platform. Built from reinforced composite material, this grip features integral finger grooves and texturing designed to keep your hand planted even when conditions turn wet or muddy. The extended beavertail geometry lets you seat your grip higher on the receiver, improving control and consistency through rapid fire strings—a meaningful upgrade if you're running precision drills, competition courses, or field work where hand position matters.

What sets the AG-43 apart is its purposeful ergonomic design. The finger swells and textured backstrap work together to reduce hand fatigue and slippage, while the beavertail extension naturally encourages a firm, high grip that translates to better recoil management and shot-to-shot repeatability. It's the kind of small change that compounds over time—especially useful for shooters who log serious rounds or need reliable control in variable conditions.

The grip also includes a unique storage compartment accessed via an integral insert at the base, giving you a discrete spot to stash small items without adding bulk or weight to your rifle. Installation is straightforward on any AR-platform upper, and the aggressive ergonomic shaping suits both right- and left-handed shooters comfortably. The black finish rounds out a practical, no-nonsense accessory that rewards attention to detail.
