The Talley Picatinny Base for the CZ 457 is a one piece scope rail with 20 MOA of built in elevation, made for shooters who want to stretch their rimfire way out past normal distances. It is machined specifically for the CZ 457 and its 11mm dovetail receiver, so it drops on and lines up without guesswork. If you are building a precision 457, this rail is the right foundation.
Who the Talley Picatinny Base Is Built For
The CZ 457 has become a favorite platform for precision rimfire competition and long range .22 practice, and both games demand serious elevation from your optic. Rimfire trajectories drop fast, so a scope mounted on a flat rail can run out of adjustment before you reach the far targets.
That is exactly the problem this base solves. Its 20 MOA of forward cant shifts your scope’s usable elevation toward the far end, keeping more adjustment in reserve for distant shots. Hunters who take longer shots on small game benefit from the same math.
Base cant is the cheapest elevation you will ever buy. Twenty minutes of angle machined into the rail saves you from running out of turret travel or holding over the top of your reticle at distance. It is the standard move on every serious long range rimfire build for a reason.
Features That Set It Apart
Made by Talley, a name rifle builders have trusted for decades, this rail is built to be mounted once and forgotten.
- One piece design that adds stiffness across the receiver
- 20 MOA of built in elevation for extended long range capability
- Machined to the MIL-STD-1913 Picatinny specification
- Cut specifically for the CZ 457 and its 11mm dovetail receiver
- Hard coat anodized finish rated to 65 Rockwell for serious durability
- Accepts any standard Picatinny rings and mounting hardware
Specs Explained in Plain Terms
The rail is machined to the MIL-STD-1913 Picatinny specification, which is the universal standard for optics mounting. That means any standard Picatinny rings, one piece mounts, or accessory hardware will clamp on with a secure, repeatable hold, and you can move optics between rifles without losing your setup.
The hard coat anodized finish is rated to 65 Rockwell, so the rail shrugs off ring marks, recoil, weather, and years of field handling without wearing through. Combined with the fitted 11mm dovetail interface underneath, the Talley Picatinny Base gives the 457 a rock solid optics platform from receiver to ring. The one piece design does quiet work here too, since a single rigid rail keeps both rings on one plane and spares your scope tube the stress of misaligned mounts.
Installation and Practical Use
Installation is straightforward because the base is made for this one rifle rather than adapted to it. Degrease the contact surfaces, seat the base on the 457 receiver, and tighten the hardware evenly to the recommended torque. From there, mount your rings and scope, and check that your optic has enough internal travel to zero at your preferred distance with the 20 MOA cant. Most variable scopes handle a standard 50 yard rimfire zero on a 20 MOA rail without complaint, so you get the long range headroom without giving up close work.
Once it is torqued down, this is a zero maintenance part. An occasional wipe with an oiled cloth keeps the finish fresh, and that is all it ever asks. Browse our apparel and gear department for rings, tools, and the rest of your precision rimfire setup.
A rifle only shoots as well as its optics mounting, and the base is where it all starts. Put a Talley Picatinny Base on your CZ 457 and give your long range rimfire ambitions the solid, canted foundation they deserve. Ships direct to your door, no FFL required.
