Ok People I really need some help here before I go mad! I have a MKIII 22/45 with over 4k rounds. Took to the range today and had all sorts of problem jamming, bolt not closing properly and all sorts. Now to top things off I CAN NOT dissasemble it! I have had this thing apart tonns of times with no effort and now I cant get the main spring out to even dissasemble it. When I rack the bolt back and use the bolt release button , the bolt does not go back it gets stuck,then I go to pull the trigger to dry fire, nothing happens? Any Ideas would be greatly appreciated, thank you!
