When they set out to build this AREA 419 wanted to solve the problem of CZ455 scope bases that slide around over time. The simple dovetail/set screw bases work for some people but they weren’t happy. This design, made from a single piece of T7075 aluminum and machined in house the AREA 419 Haas VF4SS 4 axis machining center is designed to slide onto the dovetail and be clamped down with a force that is consistent across the entire rail – and strong enough that your CZ455 will never budge it. For added security they have added a recoil lug at the rear of the base, creating a mechanical stop for the base. Bases will come Type III black hardcoat anodized and will come with the necessary 2.5mm wrench for torquing the clamp screws.
