I can tell you from recent experience that an HK93 will not function without it's extractor. Here is what happened... after 9 rounds, extractor spring breaks... 10th round, fires, but stove pipes, 11th round... nada mas. extractor is somewhere "over there"...my P7 worked just fine without it's extractor.......
would a 91 or 93 function also ? or is rifle pressure too high ?
anyone break an extractor then have a FTE ?
