FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish Review

The FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish Made a Bold First Impression

After a decade in the tactical gear world, I’ve seen trends come and go. I’ve always been a function-over-form kind of guy, but every now and then, something catches my eye that promises both. That’s how I ended up with the FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish.

I was looking for a way to improve my AR’s reload speed and overall ergonomics without going for a full-blown chassis system. My aging hands were starting to feel the strain of repetitive drills, and anything that could offer a better grip and faster mag changes was worth exploring. The advertised flared magwell and replaceable grips piqued my interest.

The packaging was standard FAB Defense – functional and no-frills. Pulling the Mojo out, the FDE polymer felt solid, though noticeably lightweight. The initial impression was surprisingly good; the design seemed well thought-out, and the grip texture looked aggressive enough to provide a secure hold.

I considered other flared magwells from Magpul and Strike Industries, both solid choices. However, the FAB Defense Mojo stood out with its unique replaceable grip system, offering a “Tactical” and “Mask” grip option. This, combined with the promise of enhanced reload speed, swayed my decision. Honestly, I was a little skeptical about the “ornamental aspect” but I was willing to see how it looked.

Initially, I was cautiously optimistic. The FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish looked good, but I needed to see how it performed under pressure.

Real-World Testing: Putting FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish to the Test

First Use Experience

My first outing with the FAB Defense Mojo was at my local outdoor range, under relatively dry and sunny conditions. I ran a series of drills focusing on rapid magazine changes and transitioning between targets. Installation was straightforward, slipping right onto my standard AR lower receiver without modification (though I did double-check compatibility beforehand, remembering the warning about potential issues with PMAG GEN3 magazines).

The flared magwell immediately made a difference; reloads felt significantly faster and smoother. Even under timed pressure, I found myself fumbling less and acquiring the magazine well with greater confidence. The “Tactical” grip felt comfortable and secure in my support hand, providing a stable platform for maneuvering the rifle.

The only initial issue I encountered was a slight wobble after installation. This was easily remedied by tightening the set screw a little further, but it’s worth noting for anyone expecting a completely seamless fit out of the box.

Extended Use & Reliability

After several months of regular use, the FAB Defense Mojo has held up remarkably well. There are no signs of cracking or deformation in the polymer, even after repeated exposure to heat and recoil. The FDE finish has shown minimal wear, and the grip texture remains aggressive enough to maintain a solid purchase.

Cleaning is simple; a quick wipe down with a damp cloth is usually sufficient. I have noticed a slight accumulation of carbon fouling around the edges of the magwell, but it’s easily removed with a brush. Compared to my previous setup (a standard magwell with no added grip), the FAB Defense Mojo has significantly improved my reload speed and overall weapon handling.

While not a revolutionary upgrade, it’s a noticeable improvement that has boosted my confidence and efficiency during range sessions.

Breaking Down the Features of FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish

Specifications

• The FAB Defense Mojo is designed for use with M16/AR-15 5.56x45mm NATO lower receivers. This makes it broadly compatible with a wide range of firearms.
• It’s constructed from a durable and lightweight fiberglass reinforced polymer. This provides a balance of strength and weight reduction.
• The FAB Defense Mojo features a flared and extended magazine well. This enhances reload speed and efficiency.
• The unit includes a system of easily replaceable grips: the “Tactical” grip and “Mask” grip. This offers customizable ergonomics and aesthetics.
• The finish is a Flat Dark Earth (FDE). This blends well with many popular AR-15 color schemes.

These specifications are important because they contribute directly to the Mojo’s functionality and user experience. The flared magwell improves reload speeds. The replaceable grips allow for customization to fit individual preferences, while the durable polymer ensures the product can withstand regular use.

Performance & Functionality

The FAB Defense Mojo excels at enhancing reload speed and improving overall weapon handling. The flared magwell significantly widens the target area for magazine insertion, reducing fumbling and missed reloads, particularly under stress.

The replaceable grips offer a customizable level of comfort and control. While the “Tactical” grip provides a more aggressive texture for enhanced purchase, the “Mask” grip (which I found less useful) is included for those who prefer a smoother feel.

The only area that could be improved is the initial wobble I experienced during installation. A tighter fit would inspire greater confidence out of the box. Overall, the FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish meets and slightly exceeds expectations.

Design & Ergonomics

The FAB Defense Mojo’s design is both functional and aesthetically pleasing. The FDE polymer is well-molded and provides a comfortable grip surface. The overall weight is negligible, adding no noticeable bulk to the rifle.

The installation process is simple and requires no specialized tools. The replaceable grips are easy to swap out, allowing for quick customization. The FAB Defense Mojo is generally very user-friendly.

Durability & Maintenance

The fiberglass reinforced polymer construction of the FAB Defense Mojo suggests excellent long-term durability. After several months of use, there are no signs of cracking, chipping, or significant wear.

Maintenance is straightforward; a simple wipe-down with a damp cloth is all that’s required to keep the Mojo clean and functioning properly. The polymer is resistant to most common cleaning solvents, adding to its longevity.

Accessories and Customization Options

The FAB Defense Mojo Mag-Well with Replaceable Grips 5.56x45mm NATO Polymer FDE Finish comes with the two mentioned grips: “Tactical” and “Mask”. There are no included accessories beyond those grips.

Due to its standard AR-15 lower receiver interface, the FAB Defense Mojo is compatible with a wide range of magazines and other accessories. Note the warning that it may not work well with PMAG GEN3 magazines. It will not, however, work with lowers that already have a built in flared magwell from the factory. There are no other specific customization options available for the Mojo itself beyond the included grips.
