Area 419 CZ 457 Scope Base

The engineers at Area 419 set out to solve the problem of CZ457 scope bases that slide around over time. The simple dovetail/set screw bases work for some people but they weren’t happy.

This design, made from a single piece of T7075 aluminum and machined in house on their 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 CZ457 will never budge it.  Bases will come Type III black hardcoat anodized and will come with the necessary 2.5mm wrench for torqueing the clamp screws.  Recommended torque spec: 22 in/lb (2.5 NM)

The rail comes in a 30MOA cant as it is meant for guys pushing their 22LRs out to 300+ yards. We also 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 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 they are good guys, and the machine would already be working in the area, they 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.

    Thank you Area 419 and Anarchy Outdoors for the high quality mounting base. The fit and finish appear as if it was designed by CZ. The level in the back of the base is genius! Makes scope mounting and level shooting much easier.

    Fit perfectly on my new 457 MTR. Great addition to my gun and plenty of room to adjust for distance. Would highly recommend this product for your CZ.

    This is great! I put in on a CZ 457 rail & it fit perfectly with 4 very positive locking screws that will never loosen even with very light tightening. Doesn’t take much. My scope ring choices were vastly improved & it allowed me to move scope forward at least 1 1/2”. Very nice.
