Area 419 CZ457 1913 Improved Scope Rail 7075 Alum 50MOA Type III Black 419-ISR-CZ457-50

11mm Dovetail

This design made from a single piece of T7075 aluminum and machined in house on AREA 419's 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 wrench for torquing the clamp screws.

The AREA 419 rail comes in a 50MOA cant as it is meant for guys pushing their 22LRs beyond 300+ yards. It is also available in a 15MOA and a 30MOA configuration. AREA 419 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.
