It supercedes the older CZ 455 rifle by offering an adjustable trigger 8-15n pull, 12n reset and 0.5-5mm travel, short 60 degree bolt throw and factory bedding for improved support & accuracy. It will be chambered in .22LR, .22WMR & .17HMR.
As shown above it is the CZ 457 MTR. And here is a scanned copy of their upcoming 2019 brochure showing other 457 variants.
