Just an update:
After receiving my form-1 tax stamp back I completed my suppressor and put it on the Scorpion for some quiet fun. It ACTUALLY sounds like “pew pew pew” if you are down range as the subsonic rounds fly by!
It is still a tack driver with subsonic 147gr rounds, but I will admit to being a little disappointed at how quickly they run out of steam. 200yds is a 3’ holdover with the red dot sight. Yes, I know it’s not a long range gun, but have been enjoying finding the limits of it anyway. It does better with supersonic rounds, but you get the “crack” instead of the “pew”.
