Area 419 Scope Base Features The Area 419 Scope Base is CNC machined from a single piece of T7075 aluminum and designed to slide onto the CZ457 s 11mm dovetail clamping down with force that stays consistent across the entire length of the rail. This 50 MOA cant is built specifically for shooters pushing their rimfire rifles past 300 yards where that much elevation reserve becomes necessary. The base also adds extra rail real estate to the front allowing the optic to be moved forward for better eye relief with higher powered scopes paired against a smaller rimfire stock. Finished in Type III black hardcoat anodize it ships with the wrench needed to properly torque the clamp screws. This base sits slightly taller than typical set screw mounts adding roughly half an inch of height to the dovetail so pairing it with lower height rings or mounts helps maintain a comparable bore height and a solid cheek weld without needing a riser. At 8.5 inches long and only 0.2 pounds it is a lightweight addition that does not unbalance a rimfire rifle s handling. The MIL-STD 1913 Picatinny pattern on top accepts standard rings and mounts simplifying optic selection. This combination of precision machining and rimfire specific design makes it a strong option for CZ457 owners chasing long range accuracy.
