"All around a great by for me, the body is nice and heavy, the gear box needed tuning (correct aoe, shimming, motor height) the body itself is nice, all trades and skull is ingraved into the body, the pain of the body scratches easy though. The grip is fantastic for right hand shooters, especially ones with big hands like me, so comfortable, all around good buy if you know what your doing and right handed.

"The metal receiver/body is very nice, the inside is piece of junk(need upgrades). I only field once with it, I don't know how the chrono on the field says 330fps, maybe it's just the chronograph. It has a really bad trigger response, I decide to open the gearbox, everything looks fine inside but the piston teeth(plastic) are already worn out(went through about 5k bbs, field&backyard). Needs correction on the AOE(angle of engagement)
Buy it if you have experience with gearbox upgrades.
