The most potent round in the Byrna lineup. Byrna .68 Cal Max Projectiles are chemical-irritant rounds built for maximum stopping power — Byrna's most powerful proprietary blend, combining OC (pepper) and CS in a single projectile.
On impact, the projectile bursts and releases a cloud of chemical irritant that rapidly disperses around the point of impact. The effect is fast-acting: irritant exposure causes intense burning of the eyes, throat, and lungs, coughing, and difficulty breathing — physical symptoms that typically disorient an aggressor and create the opening you need to get to safety.
Compatibility. These are .68 caliber rounds and work with every .68 cal Byrna launcher — the Byrna SD, Byrna LE, and Byrna Mission 4.
What's in the pack: one 5-count tube of .68 cal Byrna Max projectiles. A practical top-up or carry-spare quantity.
Honest notes. Max is a chemical-irritant round — it is a less-lethal defensive tool, not a toy and not risk-free. Use it lawfully, for defense only. It cannot be shipped to several states and cities — check your local law before ordering. Store sealed, cool, and away from children, and keep a chemical-decontamination plan on hand, since irritant clouds affect everyone nearby, including the user. Pair with training rounds so your first time firing an irritant round isn't during an emergency.
Best for Byrna SD, LE, and Mission 4 owners who want the most potent defensive round available for their launcher. Free shipping on orders over $100; 30-day satisfaction guarantee.
