Review: 11mm, 3/8inch To Picatinny/Weaver, 20mm Scope Mount Adapters - Perfect adapters to mount on a 11mm rail so you can run 20mm picatinny/weaver type scope rings instead of your standard 11mm, 3/8inch dovetail. The 20mm rings just mount alot more sturdy then the 11mm dovetail.
Review: Easy to use - I've used these in particular and this type of adapter in general on a variety of airguns. They snap right in the base of the Weaver/Pic-style ring and grab the skinny rail when the ring is tightened down. This particular make has a small vertical set screw that I've had to generally remove, I think it's for use as a recoil stop, just generally gets in the way with a continuous rail, not needed for pneumatic and PCPs. Not sure how well these inserts would work with springers. No instructions included. I make sure the short side is next to the rings' base clamps, seems to work smoother that way. This style adapter can be had from a number of vendors, this one was cheapest at the time and seems to be quality made. Have had more expensive name brand ones in bubble packs, can't see a difference. With some makes of guns, the 11mm rail is a little wider than that, I've had to disassemble the ring base clamp, put the ring and adapter on the rail and then reassemble the clamp. Not the adapter's fault, there's no real standard on those rails. This adapter does widen the variety of rings that can be used and also allows the use of optics that only have integral Pic bases. Can also be used with US-style 3/8" .22 mounts.

### ⭐ Poor Quality
*by A***R on September 30, 2024*

It fits the mount that I needed it for but it is impossible to keep it tight. It is intended to fit as a shim between two very specific widths and it does not provide a good grip on either surface.
