This video reviews the Area 419 scope base for the CZ 457 rifle, highlighting its utility for long-range rimfire shooting and competition. The base is available in 15 MOA and 30 MOA cant options, crucial for maximizing optic elevation at extended distances. A notable feature is the integrated bubble level for ensuring shot accuracy by mitigating cant. The reviewer shares personal experience using the base in a .22 competition, noting the benefit of the 30 MOA cant for reaching 400 yards.
This guide, drawing from Brownells' expertise, details the selection criteria for one-piece versus two-piece scope bases. One-piece bases offer superior rigidity and alignment, ideal for older rifles or those needing consistent ring placement. Two-piece bases enhance action clearance for easier manipulation, especially on top-loading bolt actions. For long-range precision, one-piece Picatinny rails with built-in cant are recommended.
