22 Arc 20 Inch Barrel Velocity, While the 22 ARC performs well across various barrel lengths, most ballistic testing indicates that 18- to 20-inch barrels provide the optimal balance between velocity and weapon handling characteristics. We are getting Velocity Loss numbers 25-30 FPS per Inch of Barrel. This should help folks get a baseline of what to expect Fast, lightweight, and with low drag, the new . 🔍 We break down: Velocity differences across Theoretically, a 22-inch barrel would be the best combination between somewhat manageable maneuverability and maximum velocity, but it's a non-standard length. 3152 average on 10 shots. No doubt that the ARC will have better barrel life. 22 ARC is a modern AR-15 cartridge designed to push heavy . Heavier bullets tend to have higher Measure case capacity difference between the 223 and 22 ARC and figure that approximately 1/4 of that increased capacity as a % will translate to velocity increase assuming Didn’t see a threads specifically for 6 ARC, so figured I’d get this going for people to share velocities and barrel lengths on their 6 ARC.
