Monstrum Shotgun Accessory Mount - Sling and Flashlight Combo

Our review of the Monstrum Shotgun Accessory Mount finds it a focused accessory for shooters who need a compact, integrated solution to carry a light and attach a sling on full sized shotguns. The single biggest reason to consider this mount is its combination of a one inch flashlight clamp and a quick detach sling mount in a single, lightweight unit, making it convenient for hunting, range work, or home defense setups where a secure attachment between barrel and magazine tube is required.

Key Features

• Combination Mount: Combines a 1 in diameter flashlight clamp and a quick detach sling mount so users can carry illumination and a sling from one attachment point.
• Universal Fit Aids: Includes spacing pads to adapt the mount to most standard length shotguns with a full length barrel and magazine tube, improving fitment across different makes.
• Detachable Units: Both the flashlight mount and sling mount detach independently, allowing each to be used alone or together for flexible configurations.
• Lightweight Construction: Machined from 6061 grade aluminum to keep added weight low while maintaining strength and corrosion resistance for field use.
• Secure Attachment: Designed to mount between the barrel and magazine tube to provide a stable interface without permanent modification to the firearm.

Who It's For

This mount is aimed at shooters who own full sized shotguns and want to add both a flashlight and a sling point without installing separate adapters. It suits hunters, tactical shooters, and prepper-minded owners who prefer modular accessories that can be removed when not needed.

It is not for owners of shotguns with shortened barrels or magazine tubes, and it specifically will not fit the Mossberg Shockwave or other non full-length designs; those users should look for purpose-built mounts for cut-barrel platforms.

Pros & Cons

Pros

• Includes spacing pads to improve compatibility across most full length shotguns.
• Lightweight 6061 aluminum construction balances durability with low added weight.
