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.

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!

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.

It fits a marlyn 1895 45-70
It fits on my marlyn 1895 45-70 and helps me with attaching a light on my rifle the mounting is easy to do i just add electric tape to avoid scratches on the barrel the unit feels solid and doesn't wobble when mounted correctly worth the money to me
