The Prima Sigma is a revolutionary bolt-action .223 caliber air rifle, meticulously designed with aerospace-grade steel, aluminum, and polymer to deliver exceptional durability while maintaining a lightweight, compact profile. With a minimum overall length of 35 inches and an adjustable stock, it ensures comfort and portability for a variety of applications. Its smooth bolt-action system offers seamless handling, while its compatibility with AR-15 parts, including buffer tubes, stocks, pistol grips, and handguards, allows complete customization. The fully adjustable trigger system enables fine-tuning of the first and second-stage pull and overall trigger weight for precise control.
Additional features such as an adjustable hammer spring preload, adjustable hammer face, and a thermal regulator for enhanced efficiency in cold climates elevate its versatility. Accessories like a projectile casting mold by Lee Precision, a plenum pressure regulator, and a manual high-pressure air pump further expand its capabilities. The package includes Modern Spartan “Accuracy Oil” to maintain smooth operation of friction-bearing parts.
Performance-wise, the Prima Sigma is a powerhouse, capable of firing 55-grain slugs at speeds of approximately 1,150 fps, 70-grain slugs at 1,050 fps, and 80-grain slugs at 950 fps. With energy levels reaching up to 200 foot-pounds and an effective range of 50-200 yards, it delivers consistent shot-to-shot performance with less than 3% velocity variation across 10 powerful shots from a fully charged PCP tank. These features make it an ideal choice for hunting medium to large game and precision target shooting.
The IXWA includes a reversible side-lever cocking system, positioned for easy accessibility and smooth operation. The absence of a hammer spring ensures effortless cocking across all calibers and power settings. Its large-capacity rotary stick magazine is designed to accommodate longer pellets and slugs, enabling a wider range of ammunition choices while maintaining a seamless feeding mechanism. By leveraging a pneumatic valve system, the firing cycle is drastically reduced, minimizing lock time and enhancing shot accuracy.
Safety and durability are central to the Prima Sigma’s design. It features a manual safety system for reliable user control, and its heirloom-quality materials are coated with Modern Spartan “Monster Tough” ceramic nano coatings for resistance to wear and corrosion. The rifle is also designed for easy maintenance, with replacement parts readily available and “Accuracy Oil” included to ensure long-lasting, smooth performance.
Engineered with the user in mind, the Prima Sigma is perfect for survival scenarios, hunting, target shooting, and tactical applications. It offers minimal recoil—less than a .22LR—while delivering twice the power, making it enjoyable and accessible for shooters of all skill levels. Maintenance is straightforward, requiring only a drop of Accuracy Oil with each tank refill and a quick barrel swab after each day of use, ensuring reliability and high performance in any scenario.
The Prima Sigma redefines power, precision, and versatility in an air rifle. Capable of firing projectiles at speeds of up to 1,150 fps with energy levels of 200 foot-pounds, it is perfect for hunting medium to large game with pinpoint accuracy at ranges up to 200 yards. Its 5000 PSI air tank, adjustable triggers, and AR-15 compatibility make it adaptable to meet the needs of any shooter. Its lightweight design, minimal recoil, and resistance to wear and corrosion make it a reliable, long-term companion. Backed by affordability and unmatched quality, the Prima Sigma is a game-changer in air rifle technology, offering an elite shooting experience for hunters, survivalists, and tactical enthusiasts alike.
