Well, we was wanting to get some readings on some new cans (7") today but instead we just shot a bunch of different rifles at the range. Put a test can (Arbiter) that was sent to crane naval base for eval that they tried their best to destroy and it made my little short POF 308 a COMPLETE joy to shoot. When shooting without the can the 16.5" is more than you want to hear with ear pro and WAY more than the guys next to ya! The most impressive thing was the well used Arbiter provided the same dope on four different rifles on steel at 600 yards!! We also had an AAC 7.62SD there and we shot them side by side and while I was one of the guys pulling the trigger, some of the guys behind us said the Arbiter was a smidge quieter. Now if my dang form 4 could just hurry up!
