The Fab Defense GLR-16 CP AR-15 Stock has a sleek design to prevent it from snagging or getting caught on the shooters gear. The rubber butt pad has a ribbed non slip design and allows for fast and stable shouldering. The ambidextrous quick detach sling swivel mounts allow the shooter to use a sling on either side of the stock. There are also two sling attachment slots, one in the front and one in the rear of the stock. A watertight storage compartment is big enough for two CR123 batteries. Made from a reinforced polymer composite. Includes an adjustable Cheek Rest. Fits both Mil-Spec and Commercial 6 position buffer tubes.
