MDT
CZ 457 inlet with a 6061 aluminum core, polymer panels, and adjustable crossover-stock ergonomics.
The CZ 457 XRS uses a full-length 6061 aluminum core under textured polymer panels. MDT lists the CZ 457 as a dedicated action choice and specifies factory rimfire magazines for this inlet, so it must not be confused with the separate CZ 455 105525 variants or the centerfire AICS configurations.
Add the MDT XRS Chassis System (CZ 457) to your build and see how it enhances your platform.
