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!

Perfect and secure fit to customize barrel or PCP tubes for accessories.

Had to modify but worked well on a Ruger super Wrangler 22....for the money, fantastic!

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.

Fit my 30-06 perfectly..

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

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

Item obtained was found as described, no issues or concerns. I will likely shop with this seller again.
