This is a factory POLYMER 5-round magazine for the CZ 512 rifle.
CZ topped this magazine with next-generation impact and crush resistant polymer coated with “BallisticSkin” capable of absorbing very high impact energy, extremely high tear resistance and can withstand high heat capacities whereby demonstrating ultimate toughness. Reliable is one word you can use to describe this magazine.
The enternals of this magazine include a polymer follower, and a steel compression spring to assure minimal friction and sustainability when in the field or out in the range.
Keeping a few extra factory magazines around is never a bad idea; extra magazines save loading time at the range and also serve as a backup for those days when you simply cannot remember where you put your primary magazine.
