The Lee Enfield is a Controlled Round Feed rifle.
The Lee Enfield Rifles (SMLE and other later versions for example the NO4 Mk1 and 2) are all Controlled Round Feed.
The Lee Enfield bolt controls the round as soon as it comes out of the magazine. This prevents double feeding etc.
Controlled Round Feed does not require a long non-rotating extractor, however that's the feature of the best known ones like the Mauser and its derivatives.
Many books have been written on the Lee-Enfield. Good luck.
