Description

FAB Defense built its reputation designing gear for military and law enforcement units overseas, and this GL-Core M plus Gradus combo brings two of its most useful AR15 accessories together in one Flat Dark Earth package. Instead of picking a stock and a grip separately and hoping the tones match, you get a coordinated upgrade that adds real function along with a cleaner look on your rifle.

The GL-Core M buttstock is the standout piece here. It's built around a concealed magazine carrier that holds a spare 10-round AR mag right inside the stock body, so you're never more than a few inches from a reload if your primary mag runs dry or gives you trouble. The rubberized, multi-textured buttpad locks into your shoulder for a stable cheek weld, and it ships with an interchangeable buffer tube adapter so it drops onto either Mil-Spec or Commercial tubes without extra parts to track down. Ambidextrous QD sling swivel sockets are molded right into the stock, and the whole thing is made from fiberglass-reinforced polymer to handle drops, weather, and the kind of use that gear actually sees at the range or in the field.

Rounding out the GL-Core M and Gradus pairing is the Gradus grip, a compact M-LOK foregrip that mounts flush to any M-LOK handguard slot. It's designed to work as either a stubby foregrip or a hybrid C-clamp style hold, and the slightly reduced grip angle takes pressure off your wrist during longer range days. The rubberized, multi-textured surface stays grippy whether your hands are sweaty, cold, or wet, which matters more than people think once you're a few boxes of ammo into a session.

Together, this GL-Core M and Gradus set gives you a meaningful upgrade over stock AR15 furniture, both in what it does and how it feels in your hands. It's a straightforward way to add mag storage, better shouldering, and improved grip control in one matched color scheme.

Frequently Asked Questions

What comes in the FAB Defense AR15 GL-Core M and Gradus kit?

This kit pairs the GL-Core M buttstock with the Gradus M-LOK forward grip, both finished in matching Flat Dark Earth. The stock arrives with its buffer tube adapter and a 10-round Ultimag already included, so you're not hunting down extra parts to get it installed.

Will the GL-Core M stock fit my buffer tube?

Yes, it comes with an interchangeable adapter that lets it lock onto either Mil-Spec or Commercial buffer tubes. Just make sure you install the correct adapter for your tube type before you tighten everything down.

Can I use a full-size 30-round magazine in the GL-Core M stock instead of the 10-round mag it comes with?

The carrier is sized around a compact 10-round magazine, which is what keeps the stock from feeling front-heavy or awkward on your shoulder. You technically can slot in a larger mag, but anything beyond 10 rounds adds noticeable bulk and weight to the back of your rifle.

Does the Gradus grip need a specific handguard to install?

The Gradus grip mounts directly to any M-LOK slot, so as long as your handguard has M-LOK compatible attachment points you're good to go. No rail adapter or extra hardware needed beyond what's included with the grip.
