Choose the Right JOULES
AR Tactical JOULES round balls and S-Type projectiles use iron-infused nylon formulations engineered around bore fit, projectile weight and compatible launcher performance. Use the Joules Calculator & JOULES guide to compare options. For fit testing before buying a full pack, start with the JOULES Projectile Trial Pack. HAMMER JOULES are a separate polypropylene-coated steel-core design. Always verify actual barrel bore, magazine clearance, projectile retention and launcher compatibility before use.
