Magpul Industries SGA Shotgun Stock Orange Synthetic for Mossberg 500/590/590A1

The Magpul SGA Shotgun Stock is an ambidextrous, user-configurable buttstock designed as a true drop-in replacement for Mossberg 500, 590, and 590A1 12-gauge shotguns. Built from a reinforced polymer with an orange synthetic finish, the SGA adds meaningful adjustability to the classic Mossberg pump-action platform while keeping installation quick and tool-friendly.

The SGA Stock features an adjustable length of pull from 12.50" to 14.50", allowing the shooter to dial in fit for body armor, heavy winter clothing, or different shooting positions. The ambidextrous design places the controls within reach of both right- and left-handed users, and the ergonomics are tuned to keep the trigger hand in a more natural position for faster follow-up shots on a pump-action shotgun.

Magpul's SGA installs using basic tools with no permanent modification to the host firearm required, making it an easy upgrade for a duty shotgun, a home-defense 590A1, or a Maverick 88. Sold as the stock only, it delivers a major improvement in comfort, recoil management, and control over the factory furniture.
