AR-15 users strive to get as much functionality as they can from every inch of their rifle. FAB Defense provides yet another way to make use of empty space on your AR-15 with the GL-CORE M Stock. While there are stocks available that let you store something small like extra batteries, they can't compare to the FAB GL-CORE M Stock. You can tuck an entire loaded magazine inside the stock and get on about your business. Honestly, which would you rather have in your pocket, a couple AA batteries or a loaded magazine? Especially in a tactical situation, having a spare mag in your GL-MAG Survival Stock puts you mere inches away from a mag swap. The extra weight this adds to your FAB Defense GL-CORE M Stock serves to offset a full-length barrel or all accessories you love to mount on your rail, this gives you balance.

AR-15 Stock with Mag Holder

This innovative stock has an onboard carrier for a AR-15 magazine, allowing you to store more ammunition without having to take up valuable space on your belt or tactical vest! The stock is similar in dimensions to ordinary ones, so you won't have to alter your shooting stance. Your sling can be attached to the stock using the ambidextrous connector at the rear. Mil-Spec polymer is used in construction to reduce weight and maximize strength. The streamlined design avoids snagging on gear, clothing, or other objects.

This FAB Defense AR-15 stock with mag holder is a fully adjustable six-position stock that will work on Mil-Spec or Commercial buffer tubes. It comes with an textured rubber buttpad, sporting an aggressive tread pattern. With this feature, you can be sure of a solid lock on your shoulder when you mount up to fire. Even with the FAB Defense Survival Stock in the fully collapsed position you still have easy access to your charging handle.

FAB Defense GL-CORE M Stock: Stay Engaged With One More Mag

The FAB Defense GL-MAG Stock keeps your gun ready to go without being ready to fire. If you live where you can't have a loaded gun in a vehicle, the GL-MAG Survival Stock keeps your ammo close but still legal. The FAB GL-MAG comes with a standard 10-round AR-15 mag to get you started. However, it will securely hold any standard AR-15 magazine. No stock offers both the space efficiency and the ergonomics of this FAB Defense stock with mag holder!
