keeper96 Posted January 17, 2019 Report Share Posted January 17, 2019 Hi everyone, i bought an escort mk4 at auction recently and I'm having some trouble with it. When its spotlessly clean it works fine with 32g cartridges but after about 60 shots it starts failing to feed, not a jam but it just won't feee the next cartridge as though the bolt hasn't came back far enough. After research I've found out about the famous o ring, mine doesn't have an o ring but my gas piston looks different to the others I've seen. Is the o ring missing or do the later escorts not have o rings? Jamie Quote Link to comment Share on other sites More sharing options...
Foolofatook Posted January 20, 2019 Report Share Posted January 20, 2019 Not sure about the ring question but may be an issue that the oil you're using is not standing the heat. Believe it or not a friend of mine had a similar issue,now uses Castrol rather than gun oil and in a Bennelli ! Just a suggestion. Quote Link to comment Share on other sites More sharing options...
Seadog1408 Posted January 21, 2019 Report Share Posted January 21, 2019 Maybe try it WITH an o-ring and see if it makes a difference?, mike Quote Link to comment Share on other sites More sharing options...

Croohur Posted January 21, 2019 Report Share Posted January 21, 2019 (edited) Don't have one, but watched a couple of YouTube videos as was thinking about one myself and they have all emphasised importance of the O ring and to put it on right. All Escorts have them Edited January 21, 2019 by Croohur Quote Link to comment Share on other sites More sharing options...
