UTG 590M Mag-Fed Optic Mount, 12 Gauge

• Dedicated 590M fit: Built specifically for the 12 Gauge Mossberg 590M Mag-Fed, this mount gives a secure optic platform without the compromises that often come with universal shotgun mounts.
• Full-length Picatinny top rail: The 13-slot rail provides room for red dots or other compatible optics and lets the setup be positioned for proper eye relief and balance.
• Bead sight access retained: The scalloped rail design leaves access to the factory bead sight, so the shotgun keeps a usable backup aiming reference even with the mount installed.
• Removable shell carrier: The included 4-round side saddle keeps spare shells on the gun for faster reloads, while its removable design allows the setup to be tailored to the role.
• Aluminum construction with no permanent modification: The 6061-T6 aluminum body keeps weight moderate while providing the rigidity needed for optic support, and installation does not require permanent changes to the shotgun.

About the UTG Mounts Series

UTG Mounts covers a broad range of optic-mounting solutions developed by Leapers for hunting and shooting applications. Within the brand’s lineup, the series includes dedicated mounts, rings, and rail interfaces designed to solve specific mounting problems with straightforward, durable hardware. The family is known for practical designs that focus on compatibility, repeatable fit, and sensible material choices rather than unnecessary complexity.

Across the wider series, UTG offers Picatinny-based solutions for rifles, shotguns, and optics with different footprints, alongside ring and cantilever variants for common scope tube sizes. That variety reflects a design approach centered on giving shooters a stable optic interface matched to the firearm and intended use. In the dedicated-mount segment, the emphasis is on preserving function around the host platform, maintaining access to key controls or sights where possible, and providing a mounting surface that supports modern red dots and other compact optics. For users who need a reliable bridge between firearm and sighting system, UTG Mounts are positioned as practical, purpose-built hardware.

About the UTG 590M Mag-Fed Optic Mount, 12 Gauge

The UTG 590M Mag-Fed Optic Mount, 12 Gauge is a dedicated shotgun mount built for the Mossberg 590M Mag-Fed platform. Its main role is to add a stable Picatinny rail for optics while also integrating extra ammunition storage in a compact side-mounted format. That makes it especially useful for defensive, practical, and field shotgun setups where a red dot can speed up target acquisition and on-gun spare shells help keep reloads close at hand.

The mount uses 6061-T6 aluminum with a matte black anodized finish, giving it the stiffness needed to support an optic without adding unnecessary bulk. The scalloped full-length top rail provides 13 Picatinny slots, which gives flexibility in optic placement and helps accommodate different sight sizes and mounting preferences. Just as important, the design keeps access to the bead sight intact, so the shotgun retains a simple backup aiming reference.

A removable 4-capacity shell carrier adds practical utility beyond optic mounting alone. It keeps extra shells attached to the gun for faster access, yet can be removed when a lighter or slimmer configuration is preferred. With 3.5" and under chamber clearance and installation that requires no permanent modification, the mount is designed to add capability without forcing irreversible changes to the shotgun. At 4.5 oz (128 g), it remains light enough to avoid making the gun feel overly top-heavy.

About UTG

UTG is a brand of Leapers, Inc., a company founded in Michigan in 1992. Leapers began with a compact 4×28 scope and grew into a broad shooting-sports manufacturer focused on optics and accessories. The company is headquartered in Livonia, Michigan, United States, and develops products for hunting and shooting applications across categories such as riflescopes, mounts, rings, and bipods.

Over time, Leapers expanded its technical capabilities with the launch of the UTG PRO line in 2009 and the establishment of a dedicated optics research and manufacturing center in Taiwan in 2018. That background is relevant to products like dedicated shotgun mounts, where fit, machining quality, and practical design matter as much as the raw material itself. Within this category, UTG is known for offering functional mounting solutions that address real firearm-specific needs with straightforward engineering.
