The RUSAN Picatinny Rail – 20 MOA is a precision-engineered optics mounting solution purpose-built for CZ rimfire and centrefire platforms, including the 452, 453, 455, 457, 512 and 515.

Featuring a 20 MOA forward cant, this rail allows shooters to retain valuable scope elevation adjustment, making it ideal for long-range rimfire, PRS-style competition, and precision hunting applications. By shifting the optic’s usable adjustment range, shooters gain improved ballistic flexibility and consistency at extended distances.

Manufactured to Rusan’s exacting standards, the rail delivers rock-solid stability, repeatable zero retention, and precise optic alignment. The Picatinny profile ensures compatibility with a wide range of modern scope mounts, providing a reliable upgrade for shooters seeking maximum performance from their CZ rifle.

Whether you’re building a competition-ready rimfire or refining a precision setup, the RUSAN Picatinny Rail delivers confidence where accuracy matters most.

This design, made from a single piece of T7075 aluminum and machined in house on our Haas VF4SS 4 axis machining center is designed to slide onto the dovetail and be clamped down with a force that is consistent across the entire rail – and strong enough that your CZ455 will never budge it. Bases will come Type III black hardcoat anodized and will come with the necessary wrench for torquing the clamp screws.

Recommended torque spec: 22 in/lb (2.5 NM)

Our rail comes in a 50MOA cant as it is meant for guys pushing their 22LRs out to 300+ yards. It will also be available in a 15MOA configuration. We added real estate to the front of the rail to allow you to move your optic forward. This helps on higher powered scopes when coupled with the smaller stocks that are normal on a rimfire. This base is a little taller than the popular set-screw models (our rail adds a total of about 1/2″ of height to the dovetail) but by using lower height rings/mounts you should be able to retain a similar over bore height and maintain a good cheek weld without any riser.

Since we are good guys, and the machine would already be working in the area, we decided to build in a level to the base.  The material is flared out in the area to provide optimum viewing when in the prone position without much movement if any.

Comes with stainless recoil pin to work with receivers that have the hole available, rail will still work on those that do not

As with our 700 rails, all screws are T10 Torx and the same length so no guessing which goes where

The MOA angle of the base is guaranteed to be true to the spec due to advanced fixturing

Machined to MIL-STD-1913

Type III Hardcoat Black anodized

Comes with a T10 Torx key

Screw Torque = 15in/lb

When we set out to build this we wanted to solve the problem of CZ455 scope bases that slide around over time. The simple dovetail/set screw bases work for some people but we weren’t happy.
