"this is my first gun and it is amazing. For all you people who said it fires to the left top,they are wrong, they were not looking at it correctly. I don't know how to put g-nade launcher on but i fired it with out batteries and it was stronger than the gun itself. the instructions are out dated, so don't complain the battery does not fit the way the instructions tell them to be. the PQE box is a slide on that holds the batteries, i slid mine on the top but it was not a good idea since i bought a red dot sight too.....it is made out of a thin metal and is mostly plastic, it worked even though it was rainy outside(it poured, don't ask me why i play in rain).one mag holds 50 bbs the other holds 300bbs but you must keep turning the thing on the bottom, also don't put the bbs in the same way for the300 round as the 50 round put it through the huge opining that slides. mine came within 1 week with standard ground shipping. iron sights looks like m16. great deal."
