There is objectively nothing wrong with the Lee-Enfield action.
>rear locking lugs make a much shorter bolt travel than the Mauser forward lugs, because you dont have to pull the locking lugs out of the locking recesses before the cartridge case clears the action.
>The shorter action means you dont have to move your head out of the way to cycle the bolt
>The only time it showed weakness was in the No5 Jungle Carbine, when its weight-reducing cutouts in the receiver led to 'wandering zero' accuracy problems that caused it to be withdrawn.
>Cock on closing means that you are not fighting the striker spring and doing primary extraction at the same time.
We had the Enfield P14 ready to roll in 1914 and thats an excellent rifle, but we still stuck with the Lee for two World Wars
