Monstrum Shotgun Accessory Mount V2 - Flashlight and Sling Mount

In this review of the Monstrum Shotgun Accessory Mount V2, the bottom line is simple: this is a straightforward, well-made mounting solution for shooters who run a full length barrel and magazine tube and want a dedicated flashlight and sling option. The system stands out because it combines a 1 in flashlight clamp and a quick detach sling mount on a single base that bolts to standard length shotguns, offering a clean, lightweight way to add essential accessories without heavy machining or permanent modification.

Key Features

• Compatibility: Fits most shotguns with a full length barrel and magazine tube so users can add accessories without replacing parts.
• Detachable Modules: The flashlight clamp and the quick detach sling mount both remove from the base for standalone use or to reconfigure gear quickly.
• Lightweight Construction: Made from 6061 grade aluminum to keep added weight low while retaining a durable mounting surface.
• Flashlight Fit: The 1 in diameter flashlight mount secures standard-size torches commonly used for shooting and fieldwork.
• Sling Convenience: The quick detach sling mount accepts common QD sling hardware for faster sling setup and removal in the field.
• Lifetime Guarantee: Backed by a lifetime guarantee, which provides long-term support and peace of mind for owners.

Who It's For

This mount is best for recreational shooters, hunters, and airsoft or training users who run a full length barrel and magazine tube and need a compact way to add a flashlight and QD sling interface. It suits people who prefer modular accessories that can be removed and used separately when needed.

It is not for owners of shortened-barrel platforms or the Mossberg Shockwave, or for anyone who needs a fitment that accommodates nonstandard magazine tube lengths. Those running unusual light bodies that are significantly larger or smaller than 1 in should verify fit before purchase.

Pros & Cons

Pros

• Solid build quality from 6061 aluminum provides a secure, rock-solid mounting platform.
• Easy installation and modular removability make it simple to change setups or use parts standalone.
• Lightweight design limits added bulk and helps maintain the shotgun's handling balance.
• Lifetime guarantee offers long-term confidence in the product.

Cons

• Compatibility is limited to full length barrels and magazine tubes and will not fit some shortened platforms including the Mossberg Shockwave.
• Some customers reported mixed results with certain flashlight models in brightness or fit, so light selection may require testing.

Specifications

The Monstrum Shotgun Accessory Mount V2 is a practical, lightweight solution for shooters who need a combined flashlight clamp and QD sling interface on standard length shotguns.
