Description

The FAB Defense GL-CORE IMPACT takes a well-proven stock platform and builds a shock absorber right into it. At the heart of the design is a spring-loaded mechanism sitting under the cheek riser that soaks up a good chunk of the punch before it reaches your shoulder. FAB Defense rates it at up to a 50 percent reduction in felt recoil, and while it won't change the actual energy leaving the muzzle, it makes long range sessions and heavier-recoiling setups a lot easier on your body.

What Sets the GL-CORE IMPACT Apart

The standout feature is the 3-setting adjustable mechanism. You can dial the amount of recoil reduction up or down depending on what you're running, whether that's a lighter 5.56 carbine, a bolt-action you're sighting in, or a magazine-fed shotgun throwing buckshot. That flexibility is why you'll see this stock end up on everything from AR-15 and AR-308 builds to 12-gauge platforms like the VR80.

Fit and Build on the IMPACT Stock

It ships ready to mount on any carbine-length receiver extension and includes interchangeable adapters so it locks up tight on both Mil-Spec and Commercial buffer tubes. The body is molded from fiberglass-reinforced polymer with a steel insert for strength, and it carries the same DNA as the standard GL-CORE: an integrated cheek weld, a rubberized buttpad for quick shouldering, and dual quick-detach sling swivel sockets. An inverted positioning lever keeps things from opening up on you accidentally, and the compact profile means fewer parts hanging out to snag on gear.

Getting the GL-CORE IMPACT On Your Rifle

Installation is straightforward and needs no gunsmithing. It slides on like any adjustable carbine stock, so it's a genuine drop-in upgrade whether you're refreshing an older build or finishing a fresh one. Reviewers consistently point to FAB Defense's build quality and the noticeable difference the recoil reduction makes during extended range time.

Frequently Asked Questions

Does the GL-CORE IMPACT fit both Mil-Spec and Commercial buffer tubes?

Yes. It comes with interchangeable adapters so it mounts snugly on either Mil-Spec or Commercial carbine-length receiver extensions. Commercial tabs are typically installed from the factory, and swapping them for the Mil-Spec set is quick. Note that a buffer tube is not included with the stock.

How much recoil does the IMPACT stock really reduce?

FAB Defense rates it at up to a 50 percent reduction in felt recoil thanks to the spring-loaded shock-absorbing mechanism. It softens the impact against your shoulder rather than reducing the actual recoil energy, similar to how a good recoil pad works. The three settings let you tune how firm or soft that feel is for your specific caliber.

Will the GL-CORE IMPACT work on a shotgun or an AR-308?

It will. Because it mounts to any standard carbine AR-15 receiver extension, it fits a wide range of platforms including AR-15, AR-308, and box-fed shotguns like the VR80. Just confirm your firearm uses a compatible carbine buffer tube before ordering.

Is any gunsmithing needed to install the GL-CORE IMPACT?

No gunsmithing required. It's a true drop-in replacement that slides onto your buffer tube just like a standard adjustable stock. Most people have it swapped and ready to shoot in a couple of minutes.
