The Last Magwell You Will Ever Need!
The CZ 457 rifle is renowned for its impressive engineering, offering exceptional performance and precision. However, to keep prices competitive, some corners were cut… One of these is the factory-installed plastic magwell, which is prone to cracking, especially under competitive use. Upgrade your rifle with the CZ 457 Aluminum Magwell Kit and you will never look back.
Key benefits:
-spot on tolerances with minimal free play
-ensures perfect and consistent cartridge feeding and ejection, every time
-magazines snap in with a satisfying click and fall out under their own weight when release lever is depressed
-ramp on the ejector insert and heavy chamfers on the magwell to help guide the magazine
-assembled with T10 Torx screws for maximum accuracy, rigidity and zero play
-beefed up mag release spring to prevent accidental magazine release
-compatible with most chassis systems and most 10 round magazines (if you’re unsure, please contact us)
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.
Watch our Magwell in action here:
Materials used:
-7075 aluminium for the magwell, extended release lever and ejector insert
-stainless steel pivot pin (included)
-steel T10 torx screws (included)
-enhanced mag release spring (included in kit)
note: If you purchase just the Magwell and ejector, you can use the original plastic CZ mag release lever and spring.
note 2: This magwell is only compatible with 22LR
Compatibility guide:
Will be compatible with any stock CZ rifle (LRP, MDT, American, Varmint, MTR etc, except synthetic)
Tested compatibility:
-all MDT CZ 457 chassis systems
-Vision chassis
-Rome chassis
-KRG bravo
Should be ok but untested:
-Grey Birch
Not compatible without modifications:
-PDC customs chassis: our extended mag release is slightly too wide for the opening on the chassis. Either you would have to mod out release padle or use the stock CZ mag release (or another extended aftermarket one that is thinner in width)
-R&F CZ 457 chassis (you will need to file down 3mm off the bottom of the ejector block and shorten the magazine release)
-L3i bottom metal (it covers the ejector mag block, and you would have to cut off ramp on the ejector mag block)
-Anarchy outdoors bottom metal (you will need to order the SLIM version of the mag release lever)
For chassis or bottom metals that will not fit our widened magazine release lever, order the “magwell and ejector only” and add the our “SLIM” version of the extended mag release.
MPA Vanquish Compatibility: Our magwell is not compatible with the MPA Vanquish side release without modifications.
We no longer offer this modification. You can still use our magwell in the Vanquish with our standard mag release lever.

Fell short in expectations first clips would not lock in and after removing decided to remove the mag well screws insert clip and reinstall the screws that fixed the problem next fitment is tight and small amount of scratches were easily made on the soft material overall slightly better than the aftermarket product I already had but much better than original OEM.

Thank you for your feedback. We test each magwell after assembly on 3 different magazines- The Position7 Billet Aluminium Mag, The 10rd CZ OEM magazine and the 15rd CZ OEM Magazine. So out the box, the magwell is fine tuned for the P7 and original CZ mags. The side screws are precisely there so that you can adjust the fit for other aftermarket magazines. We use 7075 aluminium for this product, which is the toughest allow readily available.

Magwell works. Paying $80+ was unexpected. $30 for fast shipping was expected. $50 for import fee was not. US suppliers are constantly out of inventory, now I see why.

Hi Josh, thanks for your review. Unfortunately, the US import tariffs are out of our control.

I’m not the best gunsmith, the CZ457 is the first actual gun i’ve done my own DIY on. (Aside from an ar15) and I would say this is a Drop in for a CZ457 American Synthetic (with very minor fitting) that you’d have to do yourself. Giant upgrade from the stock magwell. It clicks and seats the magazine nicely into place (5rnd mag) and it ejects wonderfully. Definitely a must have upgrade!
Enoc (verified owner) –
It’s a great upgrade, the best part is that it fits the CZ 455 even though Position7 doesn’t tell you this. The only killer is shipping to the USA, the tariff and shipping cost me $85

Great product. Factory magwell and release work but the Position7 Aluminum is much sturdier and the extended magwell release feels way better. Haven’t had any function issues with the 5 round factory mag or off brand 10 round mags.
