Key Features and Benefits

• Long-Stroke Piston System: Unlike direct impingement systems, the PWS piston design reduces fouling and heat transfer to the bolt carrier group, enhancing reliability and easing maintenance. This results in smoother operation and extended component life, even in adverse conditions.
• .223 Wylde Chamber: Optimized for both .223 Remington and 5.56 NATO ammunition, this chamber provides improved accuracy and versatility. Shooters can safely use a wide range of loads without compromising safety or performance.
• 11.85″ Barrel Length: The compact barrel balances maneuverability with effective velocity, making it ideal for close-quarters engagements or as a foundation for a suppressor-ready build. Manufactured from high-quality steel, it ensures durability and consistent shot placement.
• Ambidextrous Controls: Designed with left- and right-handed shooters in mind, the upper includes ambidextrous features such as a charging handle and safety selector, promoting ease of use and adaptability in dynamic scenarios.
• Monolithic Rail System: The integrated M-LOK compatible rail offers a lightweight and rigid platform for mounting optics, lights, and accessories. Its sleek design minimizes bulk while maximizing accessory real estate.
