    Your friend did something wrong, the gun would just break in half with any type of proper care.

    Op, I'm not going to say it sucks, but it's for sure not the best.

    My friend has one that he bought probably 4 months ago the only real problem to me is the blow back makes a loud metal noise when you shoot.

    Edit: you can get a warranty for it also.

    That's not necessarily true for all Dep't stores. Dick's for example sells the King Arms M4.

    My friend got didnt have the best hop up and had charging handle problems plus the dust cover wont stay up and his mag was weird like it was a REALLLLLY tight fit like he had to wiggle it in and i had to do the same when i put his mag in my masda i would say like 4/5 but on the bright side you can but it at walmart so you can just keep returning it until you get a good one

    They sell the KA sportline of sportlines. It's downgraded and junk. It's not the KA we know. The gearbox breaks very easily.

    The outside might be the same but what about the inside? My local airsoft tech had to redo everything because the gearbox split in half. You could be right because Im not sure how much stress he put on the gearbox but it couldn't be that much.

    I wish there were 10 threads about this gun with short reviews.

    No it is driven by a piece of metal screwed into the top of the piston.

    So would that wear the piston out? If so is there a way to stop the blowback?

    I'd bet you could just unscrew the screw.

    I removed all blowback related parts. I have mine running at around 35 rps with a heavier spring and some short stroking at around 380 fps and some other parts. The stock piston showed no signs of where after 50k rounds with the blowback enabled. I picked it up when it had around 45k rounds in it. The previous owner had broken the return spring for the blowback unit. The one I have is a Javelin M4 which is basically the same gun.

    Do you want to completely remove it or temporarily disable it?
