The Fab Defense GL-CORE Stock has an integrated cheek weld, an ergonomic buttpad and an interchanging tube adapter for a secure fit with Mil-Spec or Commercial buffer tubes. The adjustment lever is positioned so it will not accidentally be activated. An ambidextrous quick detach rear sling swivel is built in to the stock. Made with a light-weight fiberglass reinforced polymer composite. The CP version includes an additional Cheek Rest, designed to support the use of different optics and holographic sights on the AK and VZ platforms. On the AR platform the CP may obstruct the use of the charging handle when the buttstock is fully collapsed, for use with an AR platform, we recommend removing the CP.
