Engineered for precision rifle systems requiring a robust, repeatable optical interface, the 400-0519 is a high-performance one-piece block-style scope mount with premium materials and built-in features. Key Features: One-piece mount designed for 36 mm scope tubes; Optical Centerline height: 1.50″ (38 mm). No built-in cant (0 MIL / 0 MOA), for flat trajectory optics installations. Exterior finish: matte black. Machined from EN AW-7075 aluminium alloy, hard-coat anodised for strength and wear-resistance. Integrated foldable bubble-level (user-swappable left/right) to assist in leveling during setup. Includes mirage-band bushing, leveling wedge, and optional Picatinny rail sections for mounting ancillary tools (micro-red-dots, lasers). Why Choose the Model 400-0519? If your rifle build demands premium optical alignment and a rigid mounting platform — especially for long-range or competition applications — this mount delivers. The 0 MIL version means you don’t introduce cant compensation and instead rely on scope or turret to handle elevation. The high-quality alloy build and integrated leveling features make it ideal for high-end rifle systems where repeatability and zero-retention matter. Ideal Use Cases: Precision bolt-rifle systems where mechanical alignment and optical bore-sight are critical Competition or tactical platforms requiring premium mounting hardware Builds where a 36 mm scope tube is used and you want a single-piece block mount rather than separate rings
