Fortis Manufacturing's AR-15 LA Stock is an all-aluminum Lever Action (LA) stock that utilizes mil-spec buffer tubes. That's right - slip off the plastic stock and upgrade your rifle immediately. The lever action is what clamps down onto the buffer tube so there's no rattle or movement and their 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. Designed to attach to a standard Mil-spec diameter receiver extension (buffer tube)"" this stock easily attaches and removes without the use of tools. The real carbon fiber cheek piece adds to the overall aesthetics of the LA stock.
