Position 7 CZ457 Magazine Extension with spring

Avoid unnecessary reloads

Introducing the 457 Mag Extension, a game-changer for enthusiasts looking to enhance their shooting experience. Compatible with the original CZ 10 round magazine, this extension is specifically designed to increase your magazine capacity by 2 to 3 rounds. This means that during a 12 round stage, you can significantly reduce the need to reload, granting you the precious seconds that can make all the difference in competition scenarios.

A Must-Have for Competitors

Whether you’re a seasoned competitor or a weekend warrior, the Magazine Extension is an essential accessory for anyone who needs additional magazine capacity, without replacing all the magazines you own. Engineered for competition use, this extension ensures that you can maintain your focus on performance rather than reloading. How long does it take you to change a magazine? Probably the same time it takes to score that last point.

Customizable and Identifiable

Aside from its functional benefits, the CZ Magazine Extension comes in a variety of colors, allowing you to add a touch of personal style to your rifle setup. This feature not only enhances the aesthetics of your gear but also helps you easily identify your magazine at a glance, especially in competitive environments. With a range of colors to choose from, stand out on the field and make your mark while enjoying the advantages of increased round capacity.

Material & Manufacturing Process

This Position 7 product is 3D printed using high-quality PETG filament, a tough and reliable polymer chosen for its great balance of strength, flexibility, and weight. PETG is also thermally resistant and won’t warp under normal use — it can handle temperatures up to 80 °C (176 °F) without issues.

Because each item is 3D printed, you might notice fine layer lines or small surface marks, especially on angled or curved areas. These are a natural part of the process and don’t affect how the product performs.

Please note that this product is not made from metal. PETG is more than strong enough for its intended purpose and lighter than steel or aluminum — we use it ourselves in competition settings and stand by its performance.
