Like title states, worked just fine so far. If you are reviewing for that specific gun, than 2 of these will fit the top rail, I only needed one for my scope. They are to long but work for the other rails that surround the silencer, the silencer rails will accept them and are 2 inches long.

Great fit on a round top dovetail. The teeth are long enough and sharp enough to get a secure grip in the dovetail grooves. The only thing that needs to be changed is the finish. Although the finish is great looking, it is like a Teflon coating that slides very easily so after mounting it securely it slid with every shot. I had to sand the finish off both mounting surfaces. Overall, it's still a great product.

Product came as a (2-pack) which included (2) LONSEL 11mm Dovetail to 21mm Picatinny Rail Convert Adapter - 155mm/6.1" Long with 14 slots,: some extra screws and 2 allen keys. The adapter seemed to be well built and fit the dovetail as advertised. The package didn't come with any instructions or torque specifications. I used blue "Loctite" on the screws and snugged them to 15 in-lbs with a torque wrench. At this torque the adapter seemed to be very snug and didn't have any wiggle. The adapter is advertised as 11mm and it worked even though the dovetail I was putting it on measured 11.67mm or 0.4585 inches. After tightening the screws, as viewed from the receiver the side that is movable and tightens up against the dovetail ended up with a slight tilt or angled in toward the top of the adapter. This slight tilt may be due to the dovetail being wider than what may now be a standard width. The picatinny rail position didn't seem to be affected and appears to have remained level with the receiver. Winchester Model 250 22cal

It does exactly what it said it would, no complaints here. Super easy to use too, which is a bonus. Definitely worth the money, I'd recommend it. Five stars!

This rail was installed on a break barrel spring piston air rifle. It fitted extremely well, and the four lugs held this rail tight to the gun. After many shots the rail has not moved on the gun at all.

Don't over tighten, it holds strong. Sits a little higher then I prefer, but lower then others. A worthwhile purchase. It does the job.
