The Area 419 CZ455 1913 Improved Scope Rail 7075 Alum 30MOA Type III Black from Area 419 Firearms LLC is a one-piece, 7075 aluminum dovetail-based scope base engineered to eliminate base?slippage on CZ455 11mm dovetails. This precision part is machined in-house on a Haas VF4SS 4?axis machine and features a 30 MOA cant for extended range, making it ideal for rimfire setups aiming past 300 yards with the right optic. A rear recoil lug provides a mechanical stop for added security, and the clamp screws are torqued to a recommended 22 in/lb (2.5 NM) with a supplied 2.5 mm wrench to ensure uniform clamping force across the entire rail. The design adds front rail real estate to allow optic forward placement, improving eye relief and maintaining a consistent cheek weld on smaller rimfire stocks, while remaining taller than typical set?screw bases to accommodate lower height rings without sacrificing overbore height. The base includes a built?in level for prone stability and is compatible with CZ455 and CZ452 platforms (note: CZ American excludes this dovetail). This Type III hardcoat anodized black rail is solid and purpose?built for repeatable accuracy and hunting reliability.
