Fab Def Ar15 Tact Stock Adj Blk

The F.A.B. Defense GLR-16 Adjustable Tactical Stock for AR-15 delivers enhanced versatility through dual-diameter buffer tube compatibility, functioning seamlessly with both Mil-Spec and Commercial diameter tubes. This feature alone eliminates the common barrier that restricts many aftermarket stocks to a single platform, making the GLR-16 an exceptional choice for operators managing multiple AR-15 platforms or planning future upper receiver builds without stock replacement.

The stock's signature feature is its engineered rubber butt pad, designed specifically for fast and stable shoulder positioning during dynamic shooting. Three integrated sling attachment slots—one forward, two aft—provide flexible rigging options, while two ambidextrous QD sling swivel sockets enable rapid attachment and detachment without tool adjustment. The integrated water-resistant battery compartment accommodates two CR-123A or AA batteries, supporting modern accessory ecosystems (PEQ units, laser modules, night vision illuminators) without requiring external storage solutions.

The GLR-16 serves both patrol-ready carbines and range-focused builds where shooters prioritize modularity and operational adaptability. Law enforcement and military personnel benefit from the stock's configurability across issued weapons platforms, while serious civilian operators appreciate the multi-tube compatibility that protects investment during equipment transitions. At 0.94 lbs, the stock adds minimal weight while maintaining robust polymer construction suitable for training, duty, and defensive applications.

Tactical AR-15 stocks in this category typically sacrifice either compatibility or feature density. The GLR-16 balances both—offering practical sling mounting geometry, genuine utility storage, and universal buffer tube acceptance without requiring proprietary adapters or permanent modifications to your lower receiver.
