my G&G M4 , brand new out of box, misfeed like crazy when put the mag in,it just keep dry firing. when i remove the mag, 2 or 3 bb drop out of the mag. So i remove the mag, put the gun upside down, directly insert serveral bbs into the feeding hole~~~when i pull the trigger, the bb just jump out of the feeding hole and can not sink into the chamber!!! so anyone can tell me what should i do? i am new to airsoft so everything is new to me
