Key Features
High Capacity Operation
With a 50-round capacity, this magazine significantly extends the firearm’s operational window, reducing the frequency of reloads and maintaining target focus during critical sequences. The design prioritizes consistent feed geometry to mitigate stoppages.
Robust Polymer Construction
Constructed from a durable, clear polymer, this magazine offers both resilience against impact and chemical exposure while providing immediate visual confirmation of ammunition status. The clear material facilitates rapid inventory assessment without disassembly.
Consistent Feed Performance
Internal geometry is optimized to ensure reliable cartridge presentation to the PS90’s action. The spring and follower system are designed to maintain consistent pressure throughout the magazine’s capacity, supporting repeatable feeding cycles.
