Pulled the trigger on a MR Pintler (bag only) option on Camofire, only to find out later that MR does not sell the MT frame by itself. The old frame yes, but I would like the new and improved option. I did see a mention somewhere that sizing can be changed with a new belt/yoke. Does anyone have experience with this? There's a medium for sale, but I need a large. Do you think if I'm on the low end of the large sizing, I can squeak by with a medium?
