Magpul® SGA® Shotgun Stock – Mossberg® 500 / 590 / 590A1 12-Gauge – High-Visibility Safety Orange – MAG490-ORG
The Magpul® SGA® Shotgun Stock for Mossberg® 12-Gauge Shotguns in Safety Orange (MAG490-ORG) is a premium, highly adaptable tactical stock upgrade masterfully engineered to optimize weapon ergonomics, manage heavy 12-gauge recoil, and provide unmistakable visual designation. While traditional factory shotgun stocks feature a rigid, non-adjustable "one-size-fits-all" length of pull (LOP) that hinders fluid mounting and forces an awkward neck crane when aligning with modern optics—and standard polymer shells offer poor grip texturing under wet conditions—the SGA series thoroughly elevates smoothbore performance. This specialized tactical asset (873750008547) combines unparalleled user configuration with a durable, specialized high-visibility profile.
The structural foundation of this stock upgrade is molded from Magpul's legendary, impact-resistant reinforced polymer blend to shrug off brutal recoil shock, hard barrier strikes, and extreme environmental drops. The defining technical edge of the MAG490-ORG blueprint is its highly versatile, **user-configurable spacer system**. Utilizing the included interlocking LOP spacers, shooters can adjust the stock's length from 12.30 inches to 14.30 inches in 1/2-inch increments, allowing the user to shorten the shotgun's shoulder footprint for dynamic close-quarters work or extend it to fit larger frames perfectly. Additionally, the stock features an ergonomic, **angled grip angle texturing profile** that provides enhanced hand leverage and wrist positioning compared to standard factory lines, giving the shooter far greater muzzle control when driving the shotgun between targets.
The true functional highlight of this specific variant is its specialized High-Visibility Safety Orange coloration. Purpose-built for maritime applications, less-lethal conversion builds, training academies, and emergency search-and-rescue configurations, this bright aesthetic gives immediate visual verification of a dedicated platform layout while helping hunters remain instantly recognizable in dense woods. For recoil mitigation, the stock is outfitted with an advanced recoil-reducing butt-pad that minimizes shoulder slap during high-volume tactical strings or heavy slug drills. Complete with built-in 1.25-inch footman's sling loops on both sides and an open internal architecture that accepts modular plug-in cheek risers, this American-made workhorse delivers absolute mechanical authority and handling confidence for defensive operators.
Includes: (1) Magpul SGA Mossberg Shotgun Stock (Safety Orange), (4) Interlocking 0.50-Inch Length-of-Pull (LOP) Spacers, (1) Ergonomic Recoil Butt-Pad Assembly, and All Required High-Tensile Internal Action Mounting Screws and Hardware.
*Receiver Fitment & Gauge Compatibility Note: This MAG490-ORG module is explicitly engineered and contoured to fit factory **12-Gauge Mossberg 500, 590, and 590A1 pump-action models** utilizing the standard receiver tang. It is not compatible with smaller 20-gauge or .410 bore receivers, Maverick® 88 platforms featuring integrated slide link modifications, or hunting models utilizing top-mounted safety thumb toggles requiring custom clearance drops.
