Best Ammo for Byrna CL – Why 4.4g JOULES Are Built to Perform

Posted by AR Tactical

The Byrna CL is one of the most popular less-lethal launchers on the market today. Compact, reliable, and easy to use — it’s trusted by professionals and responsible citizens alike. But the key to making the most of your Byrna CL comes down to one thing: using the right projectile.

That’s where AR Tactical’s 4.4g JOULES come in. Engineered specifically for .61 caliber launchers like the Byrna CL, these rounds offer unmatched performance, feeding, and impact.

• Bore Size: .61 cal

• Material: Nylon 6/6 + Iron Powder + SEBS Impact Modifiers

• Color: Tactical black with reinforced shell wall

In both CO₂ and HPA testing, the 4.4g JOULES delivered consistent velocities, clean feeding, and reliable accuracy out of the Byrna CL platform. Our testers noted minimal wear and tear on internal launcher components — even after high-volume firing sessions.

Customer feedback has echoed the same: dependable, hard-hitting, and excellent fitment in both factory and modified barrels.

🛠 Launcher Compatibility

While optimized for the Byrna CL, these rounds may also fit select .61 caliber platforms. We always recommend test cycling for compatibility. For best results:

• Byrna CL – ✅ Fully compatible
