The CZ452 has two different dovetails.

The CZ452 American is a 3/8" Dovetail and requires the standard CZ452 Rail.

The same is true for the CZ452 in Varmint & FS but only for the .17HMR and .22WMR Models.

Everything else will fit the CZ455 rail, as it's 11mm

 The Parker Hale Centrefire has had quite a few iterations over the years.

The Remington 700 Long Action rail will fit as the hole spaces are:

A-B Hole: 21.89mm

B-C Hole: 113.91mm

C-D Hole: 15.41mm

Yes, it's the same as the Sako Quad

The Sako M591 has the same mounting surface as the following Sako rifles:Sako 85 S, Sako 75 III, Sako MA 05 S, Sako L579 Forester, and Sako VL63 Finnwolf

This means we have a rail in the form of the Sako 75/85 Action S / III Ultralow Rail

The Sako P94S will need the CZ455 rail.

There were an early batch of Tikka T3 rilfes that had a metric screw thread. These are M3.5x5
