Sunray is correct about the problems with 5 round SMLE magazines. My old sporterized SMLE sporter which my son now owns has a five round magazine that I bought many years ago. It was purpose built but actually had to have gunsmithing to work properly. They are out there but people who have them mostly aren't interested in selling them. By the way, my rifle was straight from factory thorough repair when I got it and I do regret converting it, though its an attractive rifle and I've taken some deer with it.
