FAB Defense FXGRADUSB Gradus 15° Ergonomic Pistol Grip with Rubber Overmold for AR-15, AR-10, M4, M16 - Black Polymer

The FAB Defense Gradus 15° ergonomic pistol grip delivers a purpose-built control solution for AR-pattern rifles in both long-range and close-quarters scenarios. Built around a reinforced polymer core with textured rubber overmold, this grip combines comfort with reliable handling during extended shooting sessions or intensive tactical drills. The 15-degree angle is deliberately modest—neither aggressive nor neutral—making it well-suited to shooters who want a balance between precision work at distance and responsive control up close.

Grip geometry matters more than many shooters realize. The Gradus was engineered with hand pressure distribution in mind: its curved backstrap and slim ergonomic profile reduce fatigue and allow your hand to settle consistently shot after shot. The textured rubber surface provides secure purchase without being so aggressive it demands gloves, and the reinforced polymer backbone ensures durability through hard use on the range or in the field. This is the kind of detail that compounds—a comfortable grip you forget about means your focus stays on the fundamentals.

FAB Defense offers the Gradus in two configurations: the beavertail version (which is what you're getting here) sits higher at the back of the receiver, and a flat option for shooters who prefer a lower profile. Compatibility spans M4, M16, AR-15, AR-10, and SR-25 platforms, so whether you're running a compact carbine or a long-range precision build, this grip will fit your system.

Frequently Asked Questions

Will this grip fit my AR-15 or AR-10?

Yes. The Gradus is designed for AR-pattern rifles including AR-15, AR-10, M4, M16, and SR-25 platforms. It uses standard AR-style grip interface, so installation is straightforward on any compatible receiver.

What's the difference between the beavertail and flat configurations?

The beavertail version (FXGRADUSB, the one listed here) extends higher up the back of the receiver for a more enclosed feel and additional support. FAB Defense also makes a flat version for shooters who prefer a lower profile without the extended backstrap.

Is this grip suitable for long-range shooting?

Yes. The 15-degree angle and ergonomic design with pressure-distributing geometry were developed specifically to support both precision long-range work and close-quarters shooting. The modest angle and textured rubber help you maintain consistent hand position session after session.

How does the rubber overmold compare to a solid polymer or stippled grip?

The textured rubber overmold provides secure, confident grip purchase without requiring gloves, and distributes pressure across your palm to reduce fatigue during extended shooting. The reinforced polymer core underneath ensures the grip holds its shape and durability through heavy use.
