Good quality, fits my H&R 20ga shotgun barrel
I purchased this clamp-on rail to fit on the barrel of my H&R 20 ga Snake Tamer shot gun. I put a weapon light on it. The mount fit perfectly. Even though the barrel has a slight taper to it, the 3-screw clamp allowed full barrel contact and after testing it with heavy load 3" mag shells, the mount and light remained unmoved. I am very happy with it. The weapon light that I placed on the mount was a "Feyachi HL-20 Pistol Light 1500 Lumen LED", which I also purchased from Amazon. The light was a great purchase at $32. It is amazing bright and can be focused from wide throw to spot. I will buy a few more. I am a retired police officer after 50+ years and I own three (3) pistol Streamlights and this beats them by brightness and price. Appears to be very well constructed. The rail mount and the Feyachi are a great combo!

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.
