Yeah it certainly works better than the factory setup! I fitted it myself, it was a bit of a guessing game as to where exactly to locate it for best ejection and you are limited by the recoil lug positioning. I also ended up making a new pin so as to have it protrude forward of the bolt face about 25 thou; to much and the case gets hooked up on it, too little and it doesn't throw the shells quite so well. Also opened up the face to accept the SAUM case and packed under the extractor.
