That’s right, Magpul is going to release their first parts for the ubiquitous 870. Look for an MOE Forend (not compatible with Super Mag) and SGA Stock at SHOT Show in booth #20163.
The MOE Forend is a drop in replacement for the factory version and features extended length and front/rear hand stops. Since it’s MOE it’s compatible with current MOE rails, mounts, and accessories.
The SGA Stock features a spacer system for length of pull adjustment, improved grip ergonomics, recoil-reducing butt-pad, optional cheek risers for use with optics/raised sights, and other accessories.
