The Last Magwell You Will Ever Need!

Why Choose the Aluminum Magwell Kit?

This kit replaces the original plastic components with high-quality materials designed for peak performance. Made from 7075 aerospace aluminum, known for its remarkable strength and toughness, the magwell upgrade is CNC machined with spark-eroded corners to achieve superior dimensional accuracy and then bead blasted and anodised. Unlike the stock plastic that may suffer from deformation/warping due to manufacturing processes, this one-piece design ensures consistency and reliability, providing you with unmatched durability.

Every Component Serves its Purpose

The CZ 457 Aluminum Magwell Kit comes with three key components: the magwell itself, an extended magazine release lever, and an ejector insert. Each part is meticulously crafted to enhance the rifle’s overall functionality. The extended magazine release mechanism allows for quicker reloads, particularly beneficial when utilizing a chassis setup. The ejector insert serves both to guide the magazine into the magwell but mainly to eject spent brass. With this rigid design, the brass ejects consistently and reliably. Finally the magwell itself is tuned to perfection. Every angle, corner and chamfer has its purpose. Whether you are in a high-pressure competitive environment or simply want a robust upgrade for your rifle, this magwell kit has you covered.

Boost your CZ 457’s reliability and performance with this essential aluminum magwell kit. Enjoy the peace of mind that comes with knowing your firearm is equipped with state-of-the-art components designed to last and provide consistent performance.
