Just feeling out the rarity/availability of a set of Micro E-mag lowers. How many of these are floating around? And how much would one go for? Also, is there any real difference between the micro e-mag lowers and the regular e-mag lowers? Never dealt with, or built an e-mag before, so I never really paid much attention, I suppose. Anyways, I'm always grateful for input. thanks
