Cleaned it up and took it to the range last night. This thing is a riot to shoot!
It cycles so fast you can make two shots sound like one long one. Its pretty much on at 50 but of course the son had to try at 100 (kids

).
Any way with open sights, standing off hand he was putting about 20% in the bull! (Damn I envy those young eyes!)
Put around 250 rounds through it and it just keeps on going.
Really glad I picked it up.
