Solid mount and easy to install
This adapter is surprisingly solid for the price. 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.

Easy to put on
Fits multiple barrels and is study enough to mount a light on.

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.

Great for the shotgun
This device is an excellent fit for my 20 gauge over/under shotgun, and a poor fit for the 44 magnum lever action rifle. I made it work on the 44 by wedging one of the edges of the device into the gap between the magazine and the barrel. I haven't fired the 44 with this device attached yet, so I can't report on how good the fit is. The fit in the 20 gauge holds well after shooting.

SHOTGUN ONLY
BOTH of these products are for SHOTGUN ONLY. The smaller one will NOT fit on a typical rifle barrel.
