FAB Defense GLR-16 CP AR-15/M16/M4 Buttstock w/Adjustable Cheek Rest & Anti-Rattle Black Polymer

The FAB Defense GLR-16 CP is a tactical collapsible buttstock designed for the AR-15, M16, and M4 platform. Built from reinforced polymer in a matte black finish, this stock combines lightweight construction with the practical features shooters look for in the FAB Defense CP line.

An integrated adjustable cheek rest lets the shooter dial in proper cheek-weld height for use with optics or iron sights, while the built-in anti-rattle mechanism locks the stock solidly on the buffer tube to eliminate wobble and noise during operation. A textured rubber butt pad provides fast, stable shoulder purchase, and integrated sling swivel studs are included for sling attachment.

The GLR-16 CP mounts to standard MIL-SPEC or commercial buffer tubes (tube not included), making it a direct drop-on upgrade for most AR-pattern rifles and carbines. Whether you are building a new rifle or refreshing an existing setup, this stock delivers tactical adjustability and dependable lockup at an accessible price.
