First, ignore the full-auto feature. It's cool, and impressive, but it won't keep you enthralled with the gun. OTOH, it's a shooter! Mine is very accurate and seems to stack anything I put through it, using only the external adjustment knob for tuning. When I first got it, it leaked - at first only so the first shot of the day was low, but eventually you could hear the air blowing out. Sent it to AoA who fixed it "perfectly" and it held air, even during extended periods of disuse (got distracted with Leshiy 2...) until I loaded it up and fired it a few times with the loading lever up - oops! Totally my fault, after a few shots the tank drained and I have not yet dug into it (still distracted by Leshiy 2) to fix yet - it's now out of warranty, so the repair at AoA held up well until I messed things up.
