Description
The Magpul Industries SGA Shotgun Stock is a drop-in replacement buttstock designed specifically for Mossberg 500, 590, and 590A1 12 gauge pump-action shotguns, and is also compatible with the Maverick 88. Molded from reinforced polymer in a low-visibility Flat Dark Earth finish, the SGA adds modern ergonomics and adjustability to one of the most widely used defensive, duty, and sporting shotgun platforms in America.
The SGA is a true fixed buttstock, but its integrated LOP Adjustment Spacer System lets the user dial length of pull from 12.30 in to 14.30 in using the included spacers, fitting a wide range of shooters and shooting positions. The ambidextrous design integrates sling loops on both sides for left- and right-handed carry, and the rugged polymer build stands up to hard use in the field, on duty, or at the range.
Installation is straightforward: the SGA drops onto the Mossberg receiver using simple tools, making it a popular upgrade for any Mossberg 500, 590, or 590A1 owner looking for improved ergonomics, sling mounting options, and length-of-pull adjustability.
