KCI USA P90 5.7x28 50-Round Magazine

P90 50-Round Magazine

This is a 50-round magazine in 5.7x28mm for the FN P90 and compatible platforms. It feeds the same cartridge from a horizontal, top-mounted position, the way the P90 was designed to run, and gives you a full combat load in a single stick. The translucent polymer body lets you check your round count at a glance, which is why these go in the pouches of anyone who shoots the platform regularly and wants a spare on hand.

Features

• 50-Round Capacity — Holds a full 50 rounds of 5.7x28mm, matching the original P90 magazine load.
• 5.7x28mm Chambering — Built for the 5.7x28mm cartridge, the small-caliber, high-velocity round the P90 was designed around.
• Translucent Polymer Body — The smoke-tinted shell lets you see how many rounds are left without pulling the magazine.
• Molded Round Count Markings — Numbered witness marks along the body show capacity at 25 and 50 for a quick check.
• Top-Mount Horizontal Feed — Sits flat across the top of the receiver and rotates rounds 90 degrees on the way in, as the P90 system requires.
• Rotary Feed Head — The dark feed assembly at the muzzle end turns each cartridge into firing position.
• P90 Platform Fit — Fits the FN P90 and firearms built to accept P90-pattern magazines.
• Polymer Construction — The one-piece polymer housing keeps the magazine light and resists corrosion.

Fit And Build

KCI USA builds this as a direct replacement for the factory P90 magazine, using the same top-mounted layout and rotary feed geometry. Confirm it drops into your specific firearm before a range trip, since P90-pattern lowers can vary slightly between makers. As a spare or a replacement for a worn original, it carries the standard 50-round load in a format the platform was built to accept.
