It is really hard to judge sound on videos but it does sound impressive. Or the lack there of is impressive. I assume that was Remington factory sub loads. I will have some test info shortly once my Form 4 arrives in a few days and I can begin testing.
damn that sounds awesome suppressed. think i might have to take a second look at getting an upper for my AR chambered in this....anyone know if you can use the same bolt, lower and buffer for the 300blk vs the 5.56?
