I just got a gas kjw m700 from a guy, it came with a super nice 40 dollar scope, and a bipod. The only problem with the gun was it was super leaky, so I tried to tighten it and the flathead screwdriver part popped off. I was sad=(, at least I was able to test it out even with it leaking gas so it works.
Everything on the gun is stock, and I was wondering what upgrades should I get for it, why, and can I fix the mag or should I keep it for spare parts?
