The machining looks clean and the metal feels sturdy, not cheap or flimsy. Installation was very simple and the included Allen key made it quick to secure everything. Once mounted it holds very tight and doesn’t shift or move, even after repeated use. The rail fits accessories properly and everything lines up the way it should. Overall it does exactly what it’s supposed to do. Good quality, simple installation, and very good value for the money. Would definitely recommend it. Review: Worked well to add a flashlight to a 20 gauge Mossburg 500 shotgun - Used this to mount a flashlight to the end of the feed tube on my old 20 gauge Mossburg 500 shotgun. I have only shot it a couple of times since adding this, but it clamped down and stayed in place well. Seems well made, solid metal. Comes with the Allen key needed to tighten it down. I can't comment on durability yet, but it seems solid. ## Features - Smart 2-piece design, easy installation, fit around the front view housing - Designed to m-o-u-n-t flashlight, laser, hand-guns, rifles, and shotgun - Ring designed to install flashlight / laser, thumb nut allows for quick installation. - The lightweight single r-a-i-l bracket is easy to install without any armory. - Durable matte black finish that can withstand harsh weather conditions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08MCS9C9P | | Best Sellers Rank | #33,902 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #17 in Airsoft Gun Scope Mounts | | Brand Name | 360 Tactical | | Color | Pack of 2 -2 | | Compatible Devices | Rifle, Shotgun | | Customer Reviews | 4.5 4.5 out of 5 stars (857) | | Item Weight | 100 Grams | | Manufacturer | 360 Tactical | | Material Type | Aluminum | | Mounting Type | Weaver Mount | | Night vision | No | | Product Style | Single Rail Three Slot Barrel Mount Weave Picatinny | | Sport Type | Hunting | ## Product Details - **Brand:** 360 Tactical - **Color:** Pack of 2 -2 - **Compatible Devices:** Rifle, Shotgun - **Item Weight:** 100 Grams - **Material:** Aluminum - **Model Name:** 360 Tactical Single Rail Three Slot Barrel Mount - **Mounting Type:** Weaver Mount - **Night vision:** No - **Sport:** Hunting - **Style:** Single Rail Three Slot Barrel Mount Weave Picatinny ## Images ![360 Tactical Universal 21mm Weaver Base Adapter Converter Barrel Scope Heavy Duty Scope - Image 1](https://m.media-amazon.com/images/I/51qeC3V3EjL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid mount and easy to install *by A***E on March 16, 2026* This adapter is surprisingly solid for the price.
