Well, I'll have a go at it. Are you trying to build a long-range, precision gun? From your mention of the Socom lower, it sounds so. If you are, a Bushmaster Varminter upper is very good. Also, Olympic PCR-1 Ultramatch uppers and Rock River Arms Varmint uppers are good too. Any of these will cost you less than the Wilson and have a free floated handguard, as well as being built ground up as a precision upper, with .223 SAAMI spec chambers, rather than the 5.56 chamber. ADCO.com sells RRA uppers, TripleBreakProducts sells Oly uppers, can't remember who sells Bushies, but look around, or check EE. The Wilsons are nice, they are well built of quality parts, their service is excellent but IMO are overpriced for what they give you. You are paying for the service, really. Most of the people I've met on this forum have uppers/guns from all manufacturers, and few have problems.
