TacFire Mil-Spec 6 Position M4 Stock Features The TacFire Mil-Spec 6 Position M4 Stock is built from durable black polymer and designed to fit mil-spec diameter buffer tubes commonly found on AR-15 platform rifles. Its six position adjustment allows shooters to customize length of pull to suit body armor clothing layers or personal preference. The stock s positive locking mechanism keeps it secure at the chosen setting during use while still allowing quick adjustments between positions. A pre-attached sling loop provides an immediate mounting point for a sling without requiring separate hardware. This stock s collapsible design makes the rifle more compact for storage transport or maneuvering in tight spaces while still locking out to a stable full-length position for accurate shooting. Its lightweight polymer construction keeps the rifle well balanced without adding unnecessary weight to the rear of the platform. As a mil-spec pattern stock it is compatible with the wide range of mil-spec buffer tubes already on the market. This makes the TacFire M4 Stock a straightforward budget-friendly option for completing or upgrading an AR-15 build.
