Dusty Stevens said:The mini m16 was a way to get a warmer feeling not having to remove so much metal from a bolt as you do with the standard
Rustystud said:The larger the cartridge the larger the extractor. This is the reason there are three different sizes. The larger extractors give you more surface area for the primary extraction to remove the fired case. You might do some research on safety test run by H.P. White Laboratories on different extractors. Remington factory style, Sako style, and M-16 Style. You will be surprised at what you find out.
