I have a Rugged Radiant 7.62 that works well, esp. for 300 Black subs. I see that Rugged has a Razor 5.56 with claims of 132 dB at the ear. I don't have test equipment, but the tests I have seen for the Radiant on a 5.56 are like 141 dB at the ear, versus the Razor 5.56 131 dB. Do you guys think Razor 5.56 would be worth it? 141 dB at the ear is still pretty good and maybe good enough versus the cost of another can, IDK. That being said, a difference 10 dB is a lot on a logarithmic scale.
