Zeiss rail

[3][1] The mounting system is now also offered on sights sold by other major manufacturers, such as Blaser,[4] Leica, Minox, Meopta, Nikon,[5] Noblex (formerly Docter[6]), Schmidt & Bender[7] and Steiner.

However, the standard prism had an aesthetic drawback in that the scope rail had to drilled on the side for attachment screws.

[citation needed] Compatible scopes have an internal dovetail rail where two or more 45-degree wedge nuts can be slid in.

[18] In late 2017,[19] Blaser released their Infinity iC (illumination Control) line of scopes which also only uses the Zeiss rail system.

[4] Aftermarket mounts compatible with the Zeiss rail system are offered by several well known manufacturers such as Blaser,[20] EAW,[9] Henneberger,[21] Innomount,[22] Kozap,[9] MAK,[23] Recknagel,[24] Rusan,[9] Uronen Precision,[25] Virtus,[26] and Ziegler.

Examples include Picatinny, Weaver or different types of claw or swing (pivot) mounts.

This can be treated like a constant term which can be added to adapt traditional scope height equations for the Zeiss rail system.

Like with traditional ring mounts, the diameter of the scope tube itself also affects the distance from the bore to the crosshair.

Swarovski applied for patent on their SR rail system in 2002,[28][29][30] and introduced to the product to the market in late 2005.

[35] Since 2016, Schmidt & Bender has also offered the Zeiss rail system as an option on some of their hunting scope sights under the name LMZ (Light Metal with Z-rail).
