And also, I hope this guy is not using a reproduction extractor and is using a usgi extractor because there is no comparison.this is a reproduction extractor that lasted a whopping 9 rounds before it failed. If I were a betting man, where the guy in the video looks young, I bet the first thing he did was put an extra power recoil spring in his carbine and those do nothing but cause problems. I have never tried one but I have read thousands of times where people do and very rarely have good results with them. These carbines have been running for over 70 years without extra power springs, so I don't know why anyone would think they need them today
