Overview
The Zastava Arms USA PAP M90 represents a refined iteration of the traditional AK platform, specifically chambered in 5.56x45mm. Manufactured in Serbia, this rifle integrates the renowned reliability of Zastava’s AK derivatives with the accessibility of modern 5.56mm ammunition. KFF Defense assesses the PAP M90 as a robust, utility-focused rifle suitable for dynamic applications requiring consistent performance and adaptable ergonomics. Its design incorporates practical enhancements for the contemporary shooter while retaining the core durability characteristic of the AK operating system.
Key Features
Caliber Integration and Operating System
Chambered in 5.56x45mm (.223 Remington), the PAP M90 leverages a commonly available and effective cartridge within the proven long-stroke gas piston operating system. This configuration ensures reliable cycling across a spectrum of ammunition types. The adjustable gas system allows operators to fine-tune the rifle’s function, optimizing extraction and recoil impulse, particularly beneficial when integrating sound suppressors or managing varying ammunition pressures.
Barrel Construction
The rifle features an 18.25-inch cold hammer-forged barrel, a process known for producing superior bore concentricity and material density, enhancing both accuracy and service life. A chrome-lined bore and chamber provide increased corrosion resistance and facilitate cleaning, crucial for maintaining long-term reliability in diverse operating conditions. The barrel is equipped with the standard 14×1 LH thread pitch, allowing for direct attachment of muzzle devices, including flash hiders, compensators, or suppressors.
Receiver and Furniture
The PAP M90 utilizes a robust stamped steel receiver, a design hallmark of the AK platform, providing a durable and resilient chassis. This model integrates Magpul Zhukov-S furniture, including a folding stock that offers compact storage and transport. The Zhukov-S stock is adjustable for length of pull and features an optimized cheek weld, significantly improving user interface and shooting posture over traditional AK furniture.
Ergonomics and Modularity
The combination of the AK’s inherent reliability with modern ergonomic enhancements elevates the PAP M90’s practical utility. The Zhukov-S stock provides a stable and adjustable shooting platform, while the rifle’s overall design facilitates accessory integration via standard attachment points (e.g., sling mounts, optics rails). The rifle is designed to accept AR-pattern magazines via a compatible magazine well, broadening ammunition supply options.
