The last three SG5-K's that I have found have all had a "$unts" magazine in them that makes the gun un-usable, I've attempted removing the mags, combining the proper magazine with the gun, taking the gun into another server and trying again, and giving the gun to a friend to see if he could do anything with it to no avail. Please help. It's one of my favorite guns it's saved my life on multiple occasions and I feel as though I am wasting space on the magazines, attachments, and ammo for the gun while looking for one.
