The PS90’s bullpup design delivers a 16.04-inch barrel in a compact package, measuring approximately 26.23 inches overall. Bottom ejection and ambidextrous charging handles and magazine release support seamless operation from either shoulder. A rotary safety positioned in the trigger guard provides intuitive control.
The barrel is cold hammer-forged and chrome-lined for durability and ease of maintenance. Factory porting and the integrated muzzle brake help manage the 5.7x28mm cartridge in this closed-bolt, blowback-operated system.
A unique, top-mounted, horizontally oriented magazine system feeds the carbine and provides a capacity of 50+1. This example includes one factory 50-round magazine.
The alloy receiver is paired with a polymer stock that incorporates an integral forward handstop and a thumbhole-style grip. A full-length MIL-STD-1913 top accessory rail runs along the receiver for mounting accessories.
