This is a sniper's dream pistol! I have had many encounters with enemies from 5 feet away and they have never even heard the gun. It is externally quiet and gas efficent. On 1 fill of propane can last you 180 shots. The mag has NO leaks and the drop leg holster has an extra mag pouch. The only issue I have had is the hop up. On externally warm days the hop has worked as it should. But on a regular day the hop dosent lift much. This has been a non issue because you draw this pistol only at very close ranges. When I used .30 in it I would have a max range of 75ft. Other than that it has been an amazing pistol. You can just not get a quiter pistol. WILLING TO TRADE for anything but would like a helmet setup or a viper hood.
