360 Tactical Universal 21mm Weaver Base Adapter Converter Barrel Scope Heavy Duty Scope

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!

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.

Put it on the barrel of my AR 15 to mount a bipod at work excellent

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

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.

Didn't work for my intended use, but may work just fine for yours.

Well i got real tired of shooting stuff with my 870 and holding a big mag lite. I live out in the sticks and have had to shoot 8 skunks and 4 coons just so far in 2018... i do alotta night time "property management" around my house. I needed a way to mount a for real weapons light (streamlight tlr1s, which i highly highly recommend also!) Onto my shotgun for hands free woods maintenance. This was the absolute perfect answer. Let me tell you i think im gonna order a few more before they realize they're giving these away at such a good price. This way exceeded my expectations, really good quality aluminum and machining. Fits a 12 gauge barrel perfectly, also would work perfectly on a 16 or 20 gauge barrel. Oh and in case you were wondering a 3" or 3 1/2" turkey shell of number 4s is the best shell you can use for all sorts of critters around the house

Mounts solid and easy to heavy M16 barrel.
