Fellow Shooters,
A few more velocities from my AR15 pistol. The temperature was 90 Degrees F and the chronograph placed 10 feet from the bench. The chronograph used was the Shooting Chrony BETA F1 Master.
Weapon- CMMG 10.3" pistol upper w/CMMG lower.

No malfunctions were noted with any of the ammunition used, including the PCA polymer cased ammunition. I didn't have time to do any accuracy testing, but I can attest that it will give 1" groups easily at 25 yards with no effort on my part.
Good Shooting
