Description
This is the factory replacement magazine for CZ 557 rifles, built to the exact specifications of the original equipment. It comes loaded with 10 rounds of capacity and uses a combination of durable steel construction paired with an impact-resistant polymer floor plate. The magazine seats cleanly in the rifle with a snug, wobble-free fit thanks to precise manufacturing tolerances that CZ's known for.
CZ 557 Magazine Construction and Reliability
The magazine body is constructed from steel and topped with a removable polymer base plate. Inside, you'll find a steel wire spring paired with an injection-molded polymer follower that works together to deliver smooth, consistent feeding across any climate or temperature range. Those numbered witness holes on the side let you count your rounds at a glance without unloading, which comes in handy when you're in the field or at the range.
Compatibility and Function
This 10-round detachable magazine works seamlessly with the CZ 557 short-action rifle in both .243 Winchester and .308 Winchester. It releases from the front of the trigger guard using CZ's standard magazine catch. Whether you're hunting or shooting at distance, the reliable push-feed system keeps rounds feeding forward dependably. The matte black finish resists corrosion and pairs well with the rifle's aesthetic.

Frequently Asked Questions
Will this CZ 557 magazine work with other CZ rifles?
This magazine is specifically designed for the CZ 557 short-action rifle in .243 and .308 Winchester. While it's built to similar standards as other CZ magazines, compatibility with other models like the CZ 550 is not guaranteed. Always verify compatibility with your specific rifle before purchasing.
Can I use this 10-round magazine in both .243 and .308?
Yes, this magazine is designed to feed both .243 Winchester and .308 Winchester cartridges reliably. The same mag works for either caliber, so you don't need separate magazines for each if you have both rifles.
What do the numbered witness holes do?
The numbered witness holes on the side of the magazine let you quickly count how many rounds are loaded without removing the magazine from the rifle or opening it up. This feature is helpful when you're in the field and need to know your ammunition status at a glance.
Is the floor plate removable for cleaning?
Yes, the polymer floor plate is removable, which makes it easier to clean the magazine if needed. You can take it off and put it back on without any special tools.
