This is a work horse of a gun. The only stock part left in the gun is the actual gear box shell. It is incredibly snappy and gets around 24-26 rps depending on the battery charge. Last I checked it was shooting 1.4j or around 390 on .2s so not currently legal for indoor use. It shoots consistent ropes due to the compression package in it. It’s been most recently tech’d on by Chris (Witch Doctor) at Low Impact Kinetics so you know it’s the real deal.
