So, I got my "AMS-Stryke series M4" today...it's crap. I paid for a King Arms BW15, I get a plastic pile of junk instead. There seems to be no metal parts except for the gearbox. Plastic receiver, plastic outer barrel, plastic buffer tube. And not quality stuff G&G uses, this is just...bad. Came with a cheap PMAG replica, I think it already broke. I thought I could at least sell some parts and get some new externals...this need more than that. It requires a big makeover, especially to get it to the BW15 I bought. Stopped shooting after one burst, found out the motor tab disconnected when I opened it up. Nothing is worth saving besides the gearbox (and even then it's not that good) and the pistol grip. Customer service was friendly, but crap. Cancelled the order after requesting to speak to a higher-up to see if I can get something better, and he blatantly lied when he said the SRC and JG G36 are "equivalents" to the King Arms. Then I was denied even the KWA CQR. Then above all that, the entire sale got cancelled after me and a bunch of fellow customers were ripped off. I would recommend no one here buy from them again, as they are less trustworthy than Tim's recommendations (that was a joke) and have become a business based on deception and disappointment. Needless to say, I gave them an "F".
