LONSEL Dovetail to Picatinny Rail Adapter 11mm Dovetail to 21mm Picatinny Rail Convert Mount - Low Profile Scope Riser Rail Adaptor - Base Mount 3/8" to 7/8" Converter

I bought this adapter so I could mount a Picatinny red dot sight on my pellet pistol, which only came with an 11mm dovetail rail. I wasn't sure what to expect at this price point, but this little adapter exceeded my expectations. Installation was quick and straightforward. It fit the dovetail rail perfectly, tightened down securely, and provided a solid Picatinny platform for my optic. Once everything was mounted, there was no noticeable movement or wobble, and my red dot held zero without any issues. The machining is surprisingly nice for such an inexpensive part. It feels sturdy, the finish looks great, and it doesn't look or feel like a bargain-bin accessory. What impressed me most was the value. For just a few dollars, it completely expanded my mounting options and allowed me to use the optic I already owned instead of buying a different sight. That's a huge upgrade for very little money. If you have a pellet gun, air rifle, or firearm with an 11mm dovetail rail and want to mount Picatinny accessories, this adapter is an easy recommendation. It fit perfectly, worked exactly as advertised, and turned out to be one of the best values I've purchased. Highly recommended!

Amazing product and price

Must have for adding new sights. Fits great and easy install. Still holding strong and holding zero for scope.

This was what I needed so I could put a thermal scope on my old 22. Easily attached and seems to hold. I did have to tighten the picatinny side of my thermal when transferring from my AR since this rail seems a little more narrow. I can’t just swap between guns without the Allen wrench.

Great with the Daisy pellet rifle.

Works well on a Winchester 190 to put a small red dot on it. Seems well made and had no problems holding zero.

The only thing I don’t like is the sitting up to high. But it fits great.

Good thing.
