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.
🚀 Recommended Round: 4.4g JOULES (.61 Cal)
We created the 4.4g JOULES with the Byrna CL in mind. The goal? Clean cycling, hard impact, and zero breakage under pressure. These rounds are injection-molded using iron-infused nylon for strength, with semi-magnetic properties that support consistent loading and firing.
Weight: 4.4 grams
Bore Size: .61 cal
Material: Nylon 6/6 + Iron Powder + SEBS Impact Modifiers
Color: Tactical black with reinforced shell wall
🔬 Test Results & Real-World Feedback
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
Byrna LE & other variants – ⚠️ Check bore clearance
