    Hey, about six months ago I bought a brand-new KWA MP7 from Toronto Airsoft. I've only fielded it once for about an hour since then (it's too cold up here in Canada), but recently, I noticed that the bbs started to curve up! I turned the hop-up down to the lowest setting, but they still curve. When I tune the hop-up up more, the bbs also curve up more. Does anyone have any idea what could be happening?

    I've had the same problem as you. What I ended up doing was getting a REAPS hop up bucking. That helped. You also might want to inspect your air nozzle for damage.

    What weight bb's are you using? I need to use .28's and up in my mp9.

    The bbs may be too light, or your bucking may be dirty. Try cleaning it with soap and water. I had this probably with my SCAR. The cleaning fixed it

    Thanks for the feedback guys, I'll try some heavier bbs (I only use .20s now), then clean the hop-up.

    UPDATE:

    Using .28s fixed the problem!
