DIP CZ 455 / CZ 457 Aluminum Magazine Well & Bumpy Extended Release Combo
Upgrade two of the most commonly handled components on your CZ rimfire with the DIP CZ-19048 aluminum magazine well and Bumpy extended magazine release combo.
Designed for compatible CZ 455 and CZ 457 rifles, this package replaces the factory magazine-well component with a CNC-machined aluminum unit and adds an extended, textured magazine release that is easier to locate and operate.
It is a straightforward upgrade for precision rimfire, NRL22-style competition, target rifles, hunting builds, and general-purpose CZ 457 setups.
Build Out Your CZ 457
DIP CZ-19048 Aluminum Magazine Well
The heart of this combo is the DIP CZ-19048 aluminum magazine well, designed as a metal replacement for the factory magazine-well component used on compatible CZ 455 and CZ 457 rifles.
Rather than relying on a molded polymer component, the DIP magazine well uses a CNC-machined aluminum construction for a rigid and durable magazine interface.
It is a simple way to upgrade a frequently handled part of the rifle while retaining compatibility with the standard CZ rimfire magazine system.
Bumpy Extended Magazine Release
This configuration also includes the Bumpy extended magazine release.
The extended profile creates a more prominent contact point than the compact factory-style release, making it easier to locate by feel when removing a magazine.
The textured Bumpy surface provides additional tactile reference so the release is easier to distinguish from the surrounding magazine-well hardware.
A More Positive Magazine Release
The factory CZ magazine release works, but its small profile can be harder to locate quickly, particularly when operating the rifle from behind the scope or during positional shooting.
An extended release provides more surface area for the finger and reduces the need to search for the release under the rifle.
That makes this combination particularly useful on rifles used for competition, high-volume range shooting, or precision-rimfire practice.
Designed for CZ 455 & CZ 457 Rifles
The DIP CZ-19048 magazine well is designed for compatible CZ 455 and CZ 457 rimfire rifles. :chatgpt-content-reference{index="1"}
Both rifles share a strong aftermarket ecosystem, making the magazine-well area a natural place to upgrade when building a rifle beyond its factory configuration.
The combo retains the familiar CZ detachable rimfire magazine system rather than converting the rifle to another magazine format.
Replace the Factory Polymer Magazine Well
One of the main attractions of the CZ-19048 is the move from the factory-style polymer magazine well to a machined aluminum component.
For shooters building a rifle with an aluminum chassis, premium laminate stock, custom barrel, upgraded bolt components, or other precision parts, the metal magazine well provides a more substantial component in an area that sees repeated magazine insertion and removal.
Useful for Precision Rimfire Competition
Magazine changes are a normal part of NRL22-style and other positional rimfire matches.
The larger Bumpy release is easier to find without significantly changing the basic operation of the CZ magazine system.
Combined with the aluminum magazine well, the package provides a practical upgrade for shooters who want the rifle's magazine controls to match the rest of a developed precision-rimfire build.
Great Upgrade for Chassis Builds
This combo is also a natural match for CZ 457 rifles installed in aftermarket chassis systems such as the MDT Oryx, ACC Premier Gen2, ACC Elite, LSS Gen3, and other compatible CZ 457 platforms.
A metal magazine well and larger release complement the more substantial feel of a chassis-equipped rifle while preserving the factory-pattern CZ magazine system.
Not Just for Competition
The benefits are equally useful on hunting, varmint, and recreational CZ 455 / 457 rifles.
A more noticeable release can be easier to operate while wearing gloves, shooting from improvised positions, or simply unloading the rifle at the end of a range session.
The aluminum magazine well also provides a durable replacement component for shooters who prefer metal hardware over the factory polymer part.
One Upgrade, Two Components
Purchasing the magazine well and extended release together makes sense because both components occupy the same area of the rifle and work together every time a magazine is inserted or removed.
Rather than upgrading the magazine well and then returning later for a more accessible release, this combo handles both at once.
