CZ 452 / 455 / 457, Tikka T1x Picatinny Rail 20 MOA - 11mm Dovetail to Picatinny

The Picatinny rail allows you to use widely available Picatinny rings. The 20 MOA canted base is ideal for .22 LR rifles and shooting from 250 yards is now possible - this is based on a scope with 75MOA elevation adjustment range (Leuopld Vx-Freedom 2-7X33 rimfire) and standard velocity ammo (1050 fps MV).  It fits the 11mm dovetail which is the standard on most European rimfire rifles and airguns.  It does NOT fit the 3/8" dovetail - the easiest way to identify the 3/8" dovetail is to measure the width of the top. If it is larger than 11mm then it is most likely a 3/8" dovetail - the old US standard for rimfire and air rifles.  Four 16mm long cross bolts are used to clamp onto the dovetail to achieve maximum stability. Also compatible with the 11mm dovetail with a rounded top (maximum height of 2.7mm). The following is an Anschutz match 64 action:  Installation is easy - simply slide this Picatinny rail onto the dovetail and tighten 4 bolts.
