Area 419 sent me their 15MOA rail and it was exactly what my CZ 457 VPC needed. This rail has an uninterrupted 6″ Picatinny rail with a 1/2″ rise providing more than enough space to mount my new Arken EP-5. Those who shoot long range tend to buy higher magnification scopes, with larger tubes, and larger objective lenses.
The EP-5 has a 56mm bell and that means extra height is required to mount the scope without it touching the barrel. In addition, this 15MOA rail has a slight downward angle effectively aiming your scope downward 15MOA. Even with this slant, the EP-5 with an extended sun shade, clears the barrel without difficulty.
I always wondered why CZ did not include a Picatinny rail adapter with their rifle when they took the effort to create a custom designed chassis for the VPC? This rifle was designed for ELR shooters, not hunters. The long range rimfire world pretty much uses the Picatinny standard when mounting optics.
But even if CZ did include their rail with this rifle, I would probably have had to replace it for the Area 419. The 419 is rail is a much better design. The CZ-made rail lacks a complete set of Picatinny slots over the full length of the rail; this limits the number of positions that you can install rings and prevents the use of scope mounts.
The Area 419 rail also has a generous cut-out arch over the CZ ejection port so as not to interfere with shell ejection (for either standard or left-handed actions). It is twice as high as the CZ rail. And best of all, it has a built-in bubble level at the rear of mount. It is the rail that CZ should have put on this rifle in the first place.
