Been rolling for a couple hours with the piston slug ammo extend mag and night vision. So far its pretty good all around. Theres been a lot of lag for me on connery this weekend so i can't attest to its lethality since most of my hits arent registering and when they do the person takes a while to actually die. My only real complaint is I think the automatic feature of the piston is pointless with slug ammo cause I find the vertical recoil unmanageable. I wish I had gotten the sweeper instead.
