I've put about 500 rounds through my new gsg and i decided its probably cleaning time. Before I did, everything was zeroed and my scope was on point - after I cleaned it, the aim was way high, about 2 feet higher at 25 yards, and was so far off that I maxed my scope out just trying to get it close. I'm new to all of this and I only have experience with pistols and airsoft guns so any help on getting my barrel back would help. Thanks!

Did you remove the scope when you cleaned it?
It sounds like you have either left something a little loose or tightened something that wasn't tight before. Go back into the weapon and check all of the screws to make sure something wasn't left loose or loosened from shooting.
Other than that it is pretty hard to diagnose your problem without either being able to see the actual firearm. Hope this helps, Skip

Thanks for the quick response. I found out that a screw was loose and was setting me off- but i'm all good now!
