xs sights Ghost Ring & Banded Standard Dot Shotgun Bead 

Ghost-Ring Shotgun sights are designed for enhanced accuracy at long distances and rapid sight acquisition for close quarters. These sights feature an adjustable windage and elevation Ghost-Ring rear sight with protective wings suitable for challenging terrains. For Mossberg shotguns lacking a front sight base, there's an easily installed Banded Standard Dot Tritium front sight, though it isn't compatible with heavy barrels, only fitting those with a diameter between 0.840" - 0.860". The Shot Rail is crafted from anodized aluminum, compatible with Weaver or Picatinny rings, and offers a straightforward installation. Made from stress-proof steel, the Ghost Ring Rear Sight is precision-machined, while the Standard Dot Banded Front Sight requires minimal gunsmithing and is the optimal choice for upgrading to rifle sights without the need for soldering or refinishing.

Gideon Optics: Alpha Red Dot Reflex Sight

The Alpha dot sight delivers a high-performance open-emitter reflex sight tailored for competition without stretching your budget. Suitable for optics-ready holsters, it features both red and green dots, a 65 MOA circle, and a precise 3MOA center dot for rapid target acquisition. Enhanced by adjustable brightness with ten settings and a battery-saving mode activated by shake-to-awake technology, it's optimal for duty or personal protection. Made from durable 7075-T6 aluminum, the same alloy used in military M-16 rifles, it aligns with Trijicon’s RMR mounting pattern and includes a 1913 Picatinny mount. Its expansive 17.5mm x 27mm lens offers a broad sight picture. Key features include 45 MOA adjustable elevation and windage, parallax-free up to 33 yards, a reticle with ten brightness levels, and 20,000-hour battery life, extendable to 50,000 hours. This motion-sensitive, shockproof, and waterproof sight ensures quick readiness and easy battery replacement. Compact in size and light in weight, the Alpha also comes with a three-year warranty.

The Mossberg 590 Mariner stands tall as an iconic shotgun, favored by many for its ruggedness and reliability. However, the world of customizations opens the door to an array of personalizations, turning this already impressive firearm into a tailored masterpiece. Whether you're aiming for a refined look, improved functionality, or both, there's no limit to what you can achieve with a custom Mossberg 590 Mariner.
