i was lazy and didnt take apart my bolt all the way when cleaning it one to many times. the result was the blot seized up. good thing Lawrence from Soecitaly Sports was out shooting with me, because i am not even close to an armor but he was one in the Gaurd. he got it up and running in a few minutes. with a little banging and some oil. as well as a lot of cleaning.
he also tought me the lesson of good mags and gave me a HK mag so i could keep my FS2000 shooting. those things are really picky on what brand mag they like. it wouldnt even use the FN mag that came with it.
