457- VS 455 Action

The 457 action is an improvement over the 455 it replaced. CZ replaced the two-lug action with a three-lug action with a shorter 60-degree bolt lift instead of the normal 90-degrees. Therefore, leaving plenty of room for the firing hand on the bolt handle throughout the cycle. The safety was also moved from the bolt shroud on the 455 to the side of the receiver on the 457. One of the greatest improvement the 457 offers over the 455 is the trigger. The 455 trigger was only tunable through the use of aftermarket spring kits, and making use of aftermarket solutions. The 457 trigger, on the other hand, is user adjustable for both weight and sear engagement. Additionally, the sear engagement is adjustable and allows the shooter to remove all discernable creep.
