Had the gun about 1.5 years. It's been a very inconsistent gun. First, it shot well on semi auto, just wasn't very efficient. At the time, full auto needed work on the gun; as it did not shoot crisp. More of pulling the trigger and the bolt shot out of control. Following this, I decided to do an hpa mod on it. I drilled and tapped the co2 cartridges in the magazines, in order to use HPA and not CO2. The mags are functional and hold air as they should, but can NO LONGER use co2. With that being said, after this mod it appears that semi auto gave out in this gun. Sometimes it shoots, sometimes it doesn't. In essence this thing needs a good tech to work on it or a nice wall to be hung on. This will also be a good parts gun for someone who already owns one. The gun is in good condition, just needs internal work from someone who knows what they're doing. Pm me for more info. I am able to ship and do PayPal. Trades will also be exercised. Price is $60 shipped.
