Ok this thing has got me baffled. It sounds loud as hell to me and I would like some input on what you peeps think.
Here is the gun:
10" 300 blackout barrel
Pistol gas with Paladin Machine Block
FailZero BCG, Ranier Upper
Can is a Liberty Black Raven II
I am running 11.5 grains of AA1680 with 220 SMK at 1050fps. Gun runs great with ejecting and BHO working on last round.
The thing sounds loud as hell to me even when I am standing away from it. I have never heard another 300 "whatever" so I have no basis. I guess I am comparing it to my Sub 308 bolt gun and the same can. There is a hell of a pop on the semi auto and does not feel hearing safe to me. Also if I shut the gas totally off it seems even louder...wtf?
Anyway if you have any input let me know. The YT Channel below has the vids of the 300 "whatever" and my 308 bolt gun with Subs and Supers. Same shitty Droid video camera about 10 foot away.
