Rusan Picatinny Rails and Scope Mounts
Rusan is a Croatian manufacturer of scope mounts, Picatinny rails, rings, and adapters for night optics. The company was founded in 1983 as a metalworking shop, shifted to gunsmithing in 1990, and began producing its own products under the name Rusan-Mikron in 2017. Today, their product range includes Picatinny rails for a wide selection of European and American rifle models, Quick Detach mounts, fixed rings, and modular adapters for clip-on night optics.
Rusan's Picatinny rails are made of solid steel with a blued (black oxide) finish. The rails are manufactured according to MIL-STD-1913 (Picatinny/STANAG 2324) with slots 5.3 mm wide and correct center-to-center spacing. Each rail is specifically adapted to the individual rifle model and comes with appropriate screws.
Choose rail by rifle model
Rusan produces rails for brands such as Tikka, Remington, Howa, Sauer, Mauser, CZ, Browning, Sako, and many more. The rails are available in various lengths and with different screw spacings, depending on the specific receiver.
It is important to choose the rail based on the exact rifle model - not just the brand. Several manufacturers have models in both Short Action and Long Action, and the placement of the screw holes varies. Always check the A/B/C measurements before ordering. A and C indicate the distance from the outer screw holes to the end of the rail, while B indicates the distance between the inner screw holes (center-to-center).

Material and surface treatment
Rusan's Picatinny rails are made of steel with bluing (black oxide) as a surface treatment. Bluing provides a dark, matte surface with a certain degree of corrosion protection. Steel is relevant when you prioritize stiffness and strength - especially with heavier optics, powerful calibers, or frequent mounting and dismounting of rings and mounts.
Rusan's tightening torque for rails is 1.8-2.0 Nm. This is lower than many other manufacturers, which is due to the precision manufacturing and the tight fit between the rail and the receiver.
MOA cant
Some Rusan rails are available with MOA cant (typically 20 or 30 MOA). A rail with MOA cant slightly angles the scope forward, providing more available elevation adjustment for shooting at longer distances.
For hunting at short and medium ranges, a rail without cant (0 MOA) is the most obvious choice. For long-range or target shooting, a rail with cant can provide better utilization of the scope's adjustment range.

Picatinny, night optics, and flexible setups
Picatinny is a standardized rail profile, which makes the system practical if you use multiple weapons or switch between different types of optics. This is especially true for thermal optics, digital night optics, and clip-on devices.
Rusan also produces modular adapters for night optics, which are mounted in front of the day sight. These adapters allow for quick and silent addition of a thermal or digital unit without changing the existing optical mount.
Many modern night vision devices can store multiple zeroing profiles, so the same unit can be used on different weapons when the correct profile is selected and the zeroing is checked.

Quick Detach mounts and rings
In addition to Picatinny rails, Rusan produces Quick Detach (QD) scope mounts and rings. The QD system allows for quick, tool-free removal and re-mounting of optics with high repeatability (Return-to-Zero).
Rusan's QD rings are available in several diameters (25.4 mm, 30 mm, 34 mm, 35 mm, 36 mm, and 40 mm) and in different heights. They are available in both steel and aluminum, depending on weight and strength requirements.
Mounting a Picatinny rail
Position the rail so that the holes align with the holes in the receiver, and tighten the screws evenly to the recommended torque (1.8-2.0 Nm for Rusan). Do not use threadlocker on Rusan rails - it is not recommended by the manufacturer.
