Magpul Industries SGA Shotgun Stock Fixed Stealth Gray Polymer for Mossberg 500/590/590A1 12 Gauge

The Magpul SGA Shotgun Stock is a drop-in replacement buttstock purpose-built for Mossberg 500, 590, and 590A1 12 gauge shotguns. Constructed from a tough, molded polymer in a low-visibility Stealth Gray finish, the SGA (Shotgun Gunner Accessory) is a fully ambidextrous, user-configurable stock designed for fast, tool-friendly installation.

The SGA features an integrated Length of Pull Spacer System that allows the user to adjust LOP from 12.30" to 14.30" using interchangeable spacers, providing a tailored fit across a wide range of shooters. A textured, angled pistol grip area, a recoil-reducing butt-pad, and optional cheek risers round out the ergonomic package. Installation is straightforward: align the receiver plate on the stock and secure it with the included receiver bolt, tightened using a standard 1/4" hex key (do not over-tighten).

This listing is for the stock only; the buttstock spacer tube is not included. The Stealth Gray colorway gives a neutral, non-reflective look that pairs well with virtually any shotgun configuration.
