I went to the range and had the extractor fail to keep the brass upon extraction. So i got many spent rounds half out with new round wedged half in. This hapened less when using my LMT bolt. This is my theiory to fix. Beef up extractor spring also add blk insert. Then go with a heavy buffer in the 7.5" lower. Possably a 9mm? to slow the extraction rate some. Anyone? Recommend a good buffer for this upper ussing a car length tube? I think im on the right track. What has worked best for u? Thanks Bill |
