Need repair

Take a picture.

Having googled the gun in question it looks very much like a VSR clone, and according to the internet it is and all parts compatible. Ive never taken the SA-S03 apart but if its like a VSR and has a VSR style hop unit, there should literally be only one way it can physically go in the gun, so fuck knows what you've managed to do to it! 

As reccomended above, when asking for help give as much information and pictures of the problem as posisble, "it broke, downside up, halp" doesnt give us much to go on.

As for places to take it to, your only realistic options from where you are is Wolf Armouries (expensive but good tech work, I've used them a few times when I've reached the "fuck it, I dont even know anymore" stage of working on my own guns) and Socom Tactical (use the shop a lot, seem like a good bunch of guys, but never used their tech work so cant comment from first hand experience)
