Slightly upgraded cyma rpk. Full metal, real wood rpk! Upgrades are: Vfc half metal rack piston, Zci cylinder head, Metal piston head, Lonex a2 motor, Wired to deans. Includes rpk bipod. I have no mags for it, but it cycles. Need minor TLC, missing rear sight, and pistol grip screw. I'm sure I'm forgetting something lol
