||this is a butterfly type stock battery which i like more because its easy to put in. It shots a little fast with .2s at about 380 right out of the box. Something weird about it was that even adjusting the hope up doesn't do much. The gun either shoots at 370-380 or like 180... had to get a spring change for my cqb arena... also a tip for getting your orange tip removed: use a blow dry on high for like 2-3 minutes and it should screw right off.
pros: great railing system
crane stock battery(adjustable to)
120 mid cap fits well
made by Socom gear so great internals
cons: shots fast (if u play at a cqb field i recommend getting a spring change)
that's all I can think of right now
