I was so excited to get this gun. When I got it, I had a couple of issues with the hop up unit, but the ASGI team was very professional about taking it back and fixing the problem. When I got it back the second time it shot great, it had a fast rate of fire and was shooting close to 380 fps, much better than it said it would shoot. On top of that it was really accurate and looks incredible. Overall as a first time customer for ASGI i was really pleased with their service and with the quality of the gun.
quick change barrel
mag capacity. I personally prefer high caps so i just got a gen 2 high cap pmag and it used the one they gave me as a back up.
