It has a piston issue. It would still cycle but with no “pop” so I am assuming it was a stripped position but not 100% sure. Comes with all of the parts. Tried to fix it, but it is too advanced for my current knowledge and too time consuming. Also comes with 3 batteries. 1 of them works. Not sure which one so I will send them all along with a charger. I also have the same brand, a CYMA electric desert eagle, fully assembled but has the same issue as this one with no “pop”. If more pictures are wanted please let me know. Have no idea what it is worth, I cannot find another sold anywhere, Make me an offer. PAYPAL Buyer pays fees, I’ll cover shipping
