BKL 167 1" Long Tri-Mount Dovetail Riser Mount - Fits 3/8" or 11mm Dovetails - Silver

It is a convenient dove tail raiser for Fx Crown air rifle (maybe for other fx's as well) to get easy alignment of scope with normal high mounting rings. In Fx's the magazine for the pellets do not allow the use of normal or medium high profile scope rings, even some of the high profile models also can not be used, so this is a handy and useful element, well made, as usual, by BKL.

I use it on my .22 CZ rifle to raise peep sight. If you squeeze them down to 11 mm, you can spread them again by putting screw in expansion hole. Read the instructions.I wish they made a 1/2” version.

These risers are very good quality (metal, fasteners, finish) but they were difficult to fit onto my Ruger American Rimfire dovetail slots. They are slightly too tight to drop right on - they must be expanded a bit with the provided screw which actually bends the metal of the base slightly so it can be placed on the gun and then the metal is bent back as you tighten them back up. I had to use a vice to hold each riser as it takes quite a lot of force to expand the bases. However, they worked out and are doing what I needed done.

rasised my scope 3/4 inch

Works great on pcp air guns but I don’t think they would hold up to any heavy recoil.

Just right!

Typical BLK high quality!
