I'm not going to lie, I monitor the sale boards pretty closely here, bought some stuff and sold some stuff, and while there's almost always a USO SN-3 of some description up for sale, I don't think I've ever seen an SN-4. Every once in a while (but pretty rare) an SN-4S. Any ideas why? Are they unpopular, or are the people who own them unwilling to give them up? I'm inclined to think the former, because no matter how awesome something is, if people were using them, they'd come up for sale occasionally.
I ask because on paper, it fits the bill perfectly for my AR, but if there's something wrong with them, or if there's a better option I'd like to hear about it.
