it is cool that the gun seems to run both just fine. I know you can't tell how quiet something really is with video, but there is definitely a big difference there.
@STFU are you satisfied with the hd762 performance with subsonic 300bo? I have a flow 762 on the way and have heard neither option is really great for 300.
For now I only have a couple of 556 gun, but would like to try out 300.
I cannot stand gas to the face.
Excellent match today, too bad we won't have any more this year
Also, mp5 mags are super easy to clean. The follower has a chrome finish and wipes right off.
