The MOE SL Stock – Mil-Spec Model (MOE Slim Line) is a drop-in replacement buttstock for AR15/M4 carbines using Mil-Spec sized receiver extension tubes. Designed for the modern battlefield, the sleek profile, dual-side release latches, rolled toe, and angled rubber butt-pad are optimized for use with body armor or modular gear and provides for efficient shoulder transitions.

Originally designed for the US military’s SOPMOD rifle enhancement program, the KAC M4 Folding Front Sight is a low-profile backup sighting solution that is designed to be attached to the top rail of a rifle’s handguard. When stowed in the folded position, the M4’s sight base extends back to envelope the front sight leaf on the right and left side, helping to protect it from damage.
