I purchased a CMMG spring kit for an ar .22 conversion kit from Midway USA.My AR conversion bolt is at least 15 years old. I got the kit and everything looked fine except the extractor spring was noticeable different. I replaced the springs and it ran horrible. I replaced new extractor spring with the old original and it ran great. I contacted CMMG customer service by the only method possible. Once they inquiried about my problem I told them the extractor spring was noticeable different, the new style functioned poorly. I told them the old extractor spring was similar to the firing pin spring, only of less diameter. They sent me an extractor. I tried to contact CMMG by phone. Impossible. I wonder why they don't say all sales are final, not responsible for any problems with parts or materials.It would save time for everybody. I don't like the idea that I have to give them a least one star.SO CMMG WHAT'S THE PROBLEM?
