Design details

As a modern civilian offspring of the Karabiner 98k
Karabiner 98k
The Karabiner 98 Kurz was a bolt action rifle chambered for the 8x57mm IS/7.92×57mm IS cartridge that was adopted as the standard service rifle in 1935 by the German Wehrmacht. It was one of the final developments in the long line of Mauser military rifles...

Operating mechanism

The operating mechanism of the CZ 550 series is based on the Mauser M 98 controlled-feed bolt action system though it is not an exact copy. The original Mauser M 98 is a simple, strong, safe, and well-thought-out design that inspired other military and hunting/sporting rifle designs that became available during the 20th century. For the CZ 550 series the action system is machined out of high-grade steel. It also features a double square bridge for mounting a telescopic sight

Features

The CZ 550 system consists of a receiver
Receiver (firearms)
In firearms terminology, the receiver is the part of a firearm that houses the operating parts. The receiver usually contains the bolt carrier group, trigger group, and magazine port. In most handguns, the receiver, or frame, holds the magazine well or rotary magazine as well as the trigger mechanism...

 that serves as the systems shroud and a bolt group of which the bolt body has three locking lugs, two large main lugs at the bolt head and the bolt handle serves as a backup in case the primary locking lugs failed. The bolt handle is permanently attached to the bolt and on the CZ 550 series and is turned-down and backwards for use with optical sights.

Another distinctive feature of the CZ 550 system is the controlled-feed mechanism, consisting of a large, non-rotating claw extractor that engages the cartridge case rim as soon as the round leaves the magazine and firmly holds the cartridge case until the round is ejected by the ejector, mounted inside the receiver. The CZ 550 bolt action will cycle correctly irrespective of the way the rifle is moved or positioned during the bolt cycling action or if the cartridge has been fired or not. Only if the bolt is not brought back far enough, sharply enough, in a controlled round feed bolt action the cartridge case may not be cleanly ejected and a jam may result.

The bolt houses the firing pin mechanism that visually and tactilely protrudes from the rear of the bolt indicating if the action is cocked or not. A small disassembly button offers the possibility to access the firing pin and spring.

The action features a large gas relief hole at the bolt body designed to protect the users head in case of a primer or cartridge rupture or detonation. When the action suffers a catastrophic failure it is designed to deflect the debris away from the operator's face.

The CZ 550 group can be easily removed from the receiver simply by pushing the disassembly button, located at the left wall of the receiver, and then by rotating and pulling the bolt out.

Safety

A horizontal 2-position safety

In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling....

 is mounted on the right side just behind the bolt system. The safety locks the bolt and sear. The user interface consists of a rather compact grooved button that should ensure good operability of the safety with low mounted aiming optics.

Trigger

The single set trigger on a CZ-550 operates as a single stage during normal operation. However, when it is desirable to have less trigger pull, such as for longer range or very accurate shooting, the trigger can be pushed forward, making it a set trigger. These rifles are factory set with the trigger pull set at approximately 15 N (3.4 lbf) in standard mode and approximately 7 N (1.6 lbf) in the set mode. Both settings are adjustable.

Ammunition feeding

For some models the internal magazine
Magazine (firearm)
A magazine is an ammunition storage and feeding device within or attached to a repeating firearm. Magazines may be integral to the firearm or removable . The magazine functions by moving the cartridges stored in the magazine into a position where they may be loaded into the chamber by the action...

 of the CZ 550 series M 98 system consists of an integral box machined to match the cartridge for which the rifle was being chambered, with a detachable floorplate, that can hold up to 5 standard sized rifle cartridges. Other models are fed by detachable box magazines, that can hold up to 4 standard sized rifle cartridges. The detachable magazines are released by a magazine release located at the front of the trigger guard.

Sights

Depending on the model various open sight are mounted as standard.
All CZ 550 receivers, except the Minnesota model, have 19 mm dove tails milled into the top of the front and rear of the receiver as factory preparation for telescopic sight mounts (bases in square bridge) or complete mounts for telescopic sight

s with or without a mounting rail.

Stock

The stocks vary from model to model and can be made out of wood or polymers.
On CZ 550 MAGNUM STANDARD, HA 550 HUNTER, CZ 550 MAGNUM LUX and CZ 550 SAFARI MAGNUM models one or two steel cross bolts are mounted to distribute the forces and hence the effects of recoil on the stock bedding, reducing the chance to spilt the stock.
