Need help with airsoft m4 purchase?

Don't buy either of them, Both D-boys and JG are very bad brands. I know you asked to not list any other guns, but please, get a G&G combat machine. You won't regret it, but you will regret getting a cheap D-boys and JG. G&G is known for their quality. Only thing is that you have to buy a battery and smart charger. I know a way to buy a G&G M4 ($140) and a battery and smart charger ($60) for less than $200 including shipping! But if your really determined on getting one of those two guns, i can't really help. You didn't list the gun name, just a description. But either way, they won't last you long and you will be out $150. Oh and i do hope you know, FPS is not quality. Hope i helped! (If you want to know my trick to saving $10- $100 then just make this best answer and say you want more info. I will either email you, or better, you can list your email and i can help you from there.
