Trinity Aluminum Saddle Mount Shell Holder & Reflex Sight Compatible with Mossberg Maverick 88 12 Gauge

Upgrade your shotgun with the TRINITY Aluminum Saddle Mount Kit featuring a Shell Holder and Reflex Sight, designed specifically for Mossberg Maverick 88 and Mossberg 500 12-gauge pump shotguns. This complete tactical upgrade enhances your shotgun with improved optics mounting capability, quick-access ammunition storage, and a precision reflex sight.

The one-piece aluminum saddle mount securely straddles both sides of the receiver, providing maximum stability under recoil. The 5.75" top Picatinny rail with 13 slots allows proper placement of optics, while the included 3.5" removable side rail offers additional mounting space for accessories such as lights or lasers.

Constructed from lightweight aircraft-grade aluminum with a non-glare black anodized finish, the mount delivers strength and durability without adding excessive weight. Installation is simple and uses the existing receiver pin ports, requiring no gunsmithing or permanent modifications.

The included Picatinny-mounted aluminum shell holder keeps five extra 12-gauge shells (2¾"–3") within easy reach, ensuring faster reloads when it matters most.

Completing the kit is a 1x reflex sight with red and green illumination, multiple reticle options, and adjustable brightness levels for quick target acquisition. Built from T6 6061 aluminum, the optic is shockproof, fog proof, and waterproof, making it ideal for range shooting, hunting, or defensive use.

Designed for reliability and versatility, this TRINITY kit prepares your shotgun for slug shooting, turkey hunting, home defense, and tactical applications.
