Historical profile
Introduced in 2019 as the successor to the CZ 455, it keeps the interchangeable barrel system (push-pin) but adds a new bolt with a reduced 60° throw for faster cycling.
The trigger is fully user-adjustable in weight (4–12 N), travel and overtravel, with a three-position safety that also locks the bolt.
Available in many configurations (Lux, Training, Varmint, Synthetic, Pro Varmint MTR, Premium, LRP), it is used in competition (rimfire PRS), sport shooting and as a .22 LR military training rifle.
