TRINITY Reflex Sight Shell Holder Combo for Mossberg 590 12 Gauge Aluminum

Upgrade your Mossberg 590 12 Gauge with the TRINITY Reflex Sight, Shell Holder, and Optics Base Combo. This complete package combines an illuminated reflex optic with convenient six-round shell storage and a durable aluminum mounting platform for hunting, target shooting, sporting, and range applications.

The included 1x reflex sight features a large 24 x 34 mm viewing window and an open tubeless design for a wide field of view and fast target acquisition. Four selectable reticle patterns can be displayed in either red or green, while **six brightness settings—three red and three green—**allow the illumination level to be adjusted for changing light conditions.

Built from T6 6061 aircraft-grade aluminum, the sight features a multi-coated lens, unlimited eye relief, and adjustable windage and elevation. Its housing is designed for shock-resistant, fog-resistant, and water-resistant performance. A CR2032 lithium battery and thermoplastic lens cover are included.

The side-mounted carrier organizes up to six 12 Gauge shells, keeping additional ammunition conveniently positioned and accessible. The integrated aluminum optics base and shell carrier are designed to install together as a complete assembly using compatible factory mounting locations.

Designed primarily for the Mossberg 500 and 590 series, the mounting assembly is also compatible with select Shockwave, 535, 835, and 590A1 configurations. Please verify mounting-hole compatibility before ordering. Pre-1997 models may use a different mounting-hole pattern and require 6-48 TPI screws, which are not included.

This TRINITY combination provides an integrated solution for shooters looking to add an illuminated optic and organized six-round shell storage in one streamlined package.
