Frequently Asked Questions

What makes the CZ 247's magazine well unique?

The CZ 247 features a distinctive rotating magazine well, inspired by the Sten Mk II. Unlike the Sten, the CZ 247's well can rotate to allow the magazine to be positioned either on the side or at the bottom, enhancing tactical flexibility for different shooting stances.

How does the CZ 247's safety mechanism work?

The CZ 247 employs a unique safety system to prevent accidental discharge from bolt bounce. A T-shaped bar integrated with the charging handle physically blocks the bolt from moving forward unless the handle is intentionally manipulated.

What is the purpose of the integrated stripper clip guide on the CZ 247?

The CZ 247 has a built-in stripper clip guide located in the buttstock. This feature acts as an integrated speed loader, allowing for faster and more efficient reloading of the 40-round magazines.

What is a progressive trigger, and how does it function on the CZ 247?

A progressive trigger on the CZ 247 allows for different firing modes based on trigger pressure. A short pull activates semi-automatic fire, while a longer, full pull engages the mechanism for fully automatic fire, eliminating the need for a separate selector switch.
