Sounds good in theory, but that not quite correct. The angled extractors are not "new".....they are actually old. Controlled round feed bolt heads used these to facilitate the rim to feed under the extractor and up into the bolt face, rather than snap over the rim.
The angled ejectors still have me baffled....the angle is the wrong way and it actually reduces the amount of travel, making things worse. Just like putting a tail on the ejector did nothing for ejection purposes. I think the general idea was to keep the spring from being crushed, but if you shoot a hot enough load to over extend the ejector, it will crush the spring, whether it has a tail in it or not.
Just another attempt at a band aid fix for a problem they don't understand. I wouldn't expect much more from engineers and techs who don't actually shoot.
