The SGA Stock is an ambidextrous, user-configurable buttstock designed to add much-needed adjustability to the tried-and-true Mossberg 500 / 590 / 590A1 12-gauge series of shotguns. Its features include a spacer system for length of pull adjustment, improved grip ergonomics, a recoil-reducing butt-pad, and optional cheek risers for use with optics/raised sights and other accessories.

The Mossberg SGA brings Magpul design and engineering to another classic American firearm.
