Area 419 Scope Base Features The Area 419 Scope Base was engineered specifically to solve the known issue of CZ 455 dovetail bases that shift position over time under recoil. Rather than relying on a simple dovetail and set screw design this base slides directly onto the factory 11mm dovetail and is clamped down with a consistent force along the entire length of the rail substantially increasing mounting strength. A recoil lug at the rear of the base creates a mechanical stop that adds further security against movement. Machined from a single piece of 7075 aluminum and finished in Type III black hardcoat anodizing the base is built to handle the stress of repeated firing without loosening. This base is cut with a 15 MOA angle giving shooters extra elevation adjustment range useful for pushing rimfire rifles out to 300 yards and beyond. A built in bubble level at the rear of the base helps shooters maintain a consistent cant for repeatable long range accuracy without needing a separate leveling accessory. The base also extends additional rail real estate toward the front allowing the scope to be positioned further forward which helps when pairing higher power optics with the smaller stocks common on rimfire rifles. For CZ 455 owners who want a scope mount that stays put and adds useful long range features this Area 419 base is a durable upgrade over the factory dovetail setup.
