Magpul SGA Black Mossberg 500/590 Shotgun Stock

The Magpul SGA Black Mossberg 500/590 Shotgun Stock is a replacement shotgun stock for compatible Mossberg 500 and 590-series shotguns. The SGA design provides a Magpul furniture option for supported Mossberg pump-action configurations in a black finish. This version is intended for users who want the platform-specific fit shown in the product name rather than a universal stock.

Confirm the shotgun model before ordering, particularly when working with variants outside the standard 500/590 family. This stock is intended as a platform-specific component for replacing or updating the rear furniture on a compatible shotgun. Because this stock is platform-specific, the exact firearm model and action or receiver pattern should be confirmed before ordering. The Black finish identifies this specific configuration.

A correctly matched stock is designed around the intended firearm geometry, so compatibility matters more than appearance when comparing similar versions. The stock can change how the firearm handles, carries, or stores, making ergonomics and interface details useful points of comparison during an upgrade. Those selection points apply specifically to the Magpul SGA Black Mossberg 500/590 Shotgun Stock, which may differ from nearby variants in size, fit, finish, or compatibility.
