Harvester evo barrel length question

[kyrifleman]

My Silencerco Harvester Evo is rated for 10" barrel in 5.56 and 16" in .308. in the decibel chart in the owners manual it shows testing with an 8.5" 300 blackout with subsonics, but doesn't say anything about 300 blackout barrel length restrictions. So my question is: are 300 blackout supersonics safe for my Harvester Evo with a 10.5" barrel? I'm sure Silencerco won't support any use not specifically stated in the manual, but practically speaking is the muzzle blast from a 10.5" 5.56 less than the muzzle blast from a 10.5" 300 blackout?

If you care about your warranty, you need to have that question answered by SilencerCo.
