This Steel Picatinny Rail is precision made by Contessa Alessandro & C. s.n.c. The part is precision made to fit the rifle with exact precision. The CZ 452 / 455 picatinny rails have a 11mm Dovetail for a flat top action. This rail slides onto the rifle, then the large fixing lugs screw down and fix the rail into place. Please note, this will not fit any Dovetail with a radius top action.
CZ Variations - American Models There are many variations of the CZ 452 / 455. There are models with a 3/8" (9.5mm) Dovetail, and there are models with a Dovetail width larger than +12mm. Usually the CZ American Models will usually have the wider size dovetail. This rail does not fit these models.
If you check the width of your rifle and if measures 11mm, this will be the correct rail for your rifle. If it measures smaller or larger than 11mm, you could potentially damage the dovetails and the rail will come off the rifle. This is why it's important to check your rifle before ordering.
