How many Actual Manufacturers are there? There is a large number of "we makes", but the uppers and lowers are mfg'd and marked by someone else. Those that CNC from solid stock such as Sun Devil aren't what I'm looking for, but rather the large "we make and will stamp (laser cut etc.) your name on the upper/lowers" types is what I'm after. The price disparity between so called manufacturers when comparing upper/lowers is interesting, especially if the price difference is strictly based on what is etched on the side! Maybe, some of the "manufacturers" are putting together some good rifles, and as such, they feel if their name is etched on the side of a stripped upper/lower (even though the don't make it, and it is identical save the name to many others) it is worth more. Strange times we live in.
