Hk-91 bolt woes, need advice
okay took out the Hk91 and shot off a clip..I noticed the cases were red hot and all smoked up, dense carbon around the base..They normally are striped and thrown a long away from the rifle...okay thought about it a while and decided it was firing with out the bolt locking..Turned it over to check the headspace,,,Normal of .005..Cycle the rifle by hand and it looks to be about .60.._ammit.what happened? Pulled it back and let it slam it went into battery, and about .005 again..So several cycles and it changes again to unlocked...I had this bolt out to clean it and you who have them know it is so -am hard to put back and get into rifle..I did not dream it could fire with such a gap.. What did I do wrong?, Can the wedge be put in upside down? I am going to test it again this weekend..if it does it anymore then, it is coming apart..I have not replaced any parts, It was filthy and i cleaned it like several times before.I am asking here as I lost my password for hk pro forum.. Little help here if you have ever noticed this flaw..Thx.OG.
