The Area 419 CZ457 1913 Improved Scope Rail from Area 419 Firearms LLC is a single-piece 7075 aluminum, 11mm dovetail mount engineered to slide onto the CZ457 dovetail and clamp securely with consistent force across the entire rail, ensuring the rifle never budges under recoil. Machined in-house on AREA 419s Haas VF4SS 4-axis center, this rail is Type III black hardcoat anodized and ships with the necessary wrench for torquing the clamp screws, delivering rugged reliability for demanding field use. Designed with a 50MOA cant, it provides extended elevation for long-range 22LR shooting beyond 300 yards, while also offering 15MOA and 30MOA configurations for versatility. AREA 419 has added real estate to the front of the rail to allow optic forward placement, a feature that helps maintain proper eye relief on higher powered scopes when paired with compact rimfire stocks; the rail is taller than typical set-screw models by about 1/2", yet compatible with lower height rings to preserve over-bore height and a solid cheek weld without a riser.
