Cantilever Block Mount – Model 400-0521 FDE

ZCO

Crafted for professional precision-rifle applications, the 400-0521 FDE is a premium one-piece block-style scope mount engineered for durability, repeatability and high-accuracy setups.

Key Features:

 

  • Designed for 36 mm scope tubes with a mounting height of 1.50″ (38 mm) optical centerline. 

  • Built-in pre-tilt of 6 MIL (≈20.6 MOA) to support long-range elevation setup. 

  • Colour: Flat Dark Earth (FDE) finish — blends well with tan/desert-chassis systems.

  • Machined from EN AW-7075 aluminium, hard-coat anodised for superior strength and wear resistance. 

  • Includes an integrated folding bubble level (swappable left/right or removable) for rapid leveling in the field. 

  • Mirage-band bushing included for thermal mitigation over the barrel. 

  • Picatinny rail compatibility: accessory mounting points for micro-red-dots or lasers. 

 


Why Choose This Mount?

If your build demands the highest mechanical interface for a scope — especially on a precision bolt rifle or long-range tactical platform — the 400-0521 delivers. The 6 MIL forward-cant helps accommodate long-range elevation without resorting to spacers or wedges; the one-piece block design enhances alignment repeatability; the FDE finish matches modern chassis systems; and the integrated level makes setup faster at the range.


Ideal Use Cases:

  • Precision rifle rigs requiring 1000 + yd accuracy

  • Tactical platforms where repeatable zero and rugged interface are required

  • Builds with tan/flat-earth chassis where color-match matters

  • Shooters who want factory-level integration of leveling and accessory-mount features
