Description

The CZ Bolt Action CZ 550 is a factory replacement bolt assembly manufactured for the CZ 550 Rifle series by Česká Zbrojovka. The CZ 550 is a traditional hunting rifle built on a Mauser-style controlled-round-feed action, widely valued for its durability and reliability in field conditions.

The bolt assembly includes the primary locking mechanism responsible for chambering cartridges, locking the action during firing, and extracting spent cases. The design incorporates two primary locking lugs and a third safety lug, along with a large claw extractor that grips the cartridge case as it leaves the magazine, ensuring controlled feeding into the chamber.
