Description
The FAB Defense AG-43 is one of those upgrades that makes a bone-stock AR feel like it was built for your hand. Swap out the flat, hard factory grip and you get molded finger grooves, a shaped backstrap, and a textured surface that keeps your hand planted whether you're running drills in the heat or working in wet weather. The extended beavertail is the standout piece here, letting you choke up high on the receiver for a firmer, more natural hold that cuts down on wrist fatigue over a long range session.
What the AG-43 Grip Brings to Your AR
FAB Defense builds this one from reinforced polymer, so it's light but tough enough to shrug off years of hard use. The texturing does double duty, giving you a non-slip surface while allowing a bit of air between your palm and the grip so your hand doesn't get sweaty and lose purchase mid-string. It fits most popular AR-15 platform rifles along with M16, M4, AR-10, and SR-25 variants, and installation is about as simple as it gets. One screw, a couple of minutes, and you're done.
Hidden Storage Inside the AG-43
The hollow core of the grip is more useful than it sounds. Pop the tight-sealing hinged door on the bottom and you've got a dry spot to stash a small vial of gun oil, cleaning patches, spare batteries for an optic, or anything else you'd rather keep with the rifle than dig for later. The door seals up snug so nothing rattles loose in the field.
Worth noting for anyone expecting a soft rubber feel: the AG-43 is a firm polymer grip rather than an overmolded rubber one, which is what gives it that durable, planted texture. It carries the FAB Defense lifetime replacement guarantee, so it's built to stick around. For folks who want a grip that improves handling without breaking the bank or the weight budget, this one earns its spot.

Frequently Asked Questions
What rifles does the AG-43 grip fit?
The AG-43 fits most standard AR-15 platform rifles as well as M16, M4, AR-10, and SR-25 variants that use a mil-spec grip mount. If your lower takes a common AR grip, this one will bolt right on. Installation takes a single screw and just a couple of minutes.
Is the AG-43 grip rubber or hard polymer?
This is a firm reinforced polymer grip rather than a soft rubber overmold. The texturing on the finger grooves and backstrap is what gives it the non-slip feel, and it also lets a little air pass between your palm and the grip to cut down on sweat. If you specifically want a rubber overmolded version, FAB Defense makes the AGR-43 for that.
What can you store inside the AG-43 grip?
The hollow core opens through a hinged, tight-sealing door on the bottom of the grip. It's a handy spot for a small vial of gun oil, cleaning patches, spare optic batteries, or other small essentials you want to keep with the rifle. The door seals snug so nothing rattles or falls out in the field.
Does the extended beavertail make a real difference?
It does. The beavertail lets you ride your hand higher and closer to the bore line for a firmer, more natural hold. Over a long range session that higher grip position helps reduce wrist strain and gives you better overall control during firing.
