JOULES™ – 4.4g – .61 Cal – 25pcs

Introducing the AR Tactical JOULES™ .61 Cal, precision-engineered exclusively for the Byrna CL platform. Measuring 15.1–15.3 mm and weighing in at 4.0 to 4.4 grams, these rounds are made from our custom iron-infused nylon—built for strength, stability, and real-world performance.
Each projectile features semi-magnetic properties, promoting smoother chambering and improved reliability in magnetic feed systems. The iron-infused material also delivers consistent energy transfer on impact while maintaining structural integrity—even at high velocities.
Specifically sized for the Byrna CL’s bore, these JOULES™ rounds eliminate the guesswork and provide tight, consistent shot patterns. Whether you’re training or defending, they’re built to perform under pressure.
