If it's going to be a SIG, it has to be Swiss- not some cheap US clone.
I think the US made guns can be brought up to par by welding on an optic rail or rear diopter, refinishing, and using Swiss furniture. The Classic and xi lower which use AR mags are a nice option for the US guns - with Swiss upper you can only use pmags (tight fit) or 20 round USGI mags. A Swiss lower really improves them. But then at what cost - one is pushing close to or more than the cost of a 553 with all these mods. I have three such Swissified US rifles and they are very nice once complete.
