||I bought one in june and have been shooting it all summer.The gearbox itself is not bad.The only thing that i've noticed that it is not shimmed and isn't greased well at all and the piston gears are plastic and got pretty chewed up.Still shoots decent though and oh ya the inner barrel came bent. ? I've upgraded the receivers to metal and i;m ordering an internal upgrade for it now.
1.Ball bearings instead of bushings.
2. M 120 190% irregular pitch spring.
3.aluminun piston with full metal teeth.
4.Madbull ultimate full metal hop up w/ led module.
5.angel stainless 6.01mm tightbore barrel.
6.O ring air seal nozzel.
7.Ball bearing spring guide.
8.70' hop up bucking.
9.Replace wiring and fuse with mosfet/ H.Q.wiring kit.
After this i should have about $400.00 including gun invested,but should be a bad and realistic gun.I looked for a high end gun that was a full top rail M4 S-System gun but this one was the best one i could find for the $.I highly recommend this gun for anyone starting or intermediate cause as you see my list it is very easily upgradable if you are a little mechanically incline and not scared of tearing the gun completely down.Once i'm done with this one i will post a review on You Tube with a video how i the upgrades were done,a itemized price list of the parts,From Evike.com of corse and a firing test.
