Fortis Manufacturing's AR-15 LA Stock is an all-aluminum Lever Action collapsible buttstock that utilizes mil-spec diameter buffer tubes. The stock's lever action is what clamps down onto the buffer tube so there's no rattle or movement and this patent pending design is one of a kind. It is designed to be lightweight and robust. This stock is made from high quality 6061-T6 aircraft grade aluminum and features an ultra-durable mil-spec hard coat anodized finish. The real carbon fiber cheek piece adds to the overall aesthetics of the LA stock, while also keeping it lightweight
