    Hi!
    I have a very strange feeding prob. when i put my high cap everything is fine but when i use my mid and fill it over 70 bbs, it spits the bbs or the gun jams. i tried marui bucking and green gng. Also i tried the original barrel and hop up and the same. My friends gun have the same prob and its full stock never opened. Maybe is the barrel hop up installation? both are gng m4 gr16

    also when it fires normally after 5 shots shoots blank

    Thank you for your reply.! I have done some on my own but I will consider vfc bucking. Does anybody know if marui buckings have thinner lips than vfc?
