First of all, THIS High Standard is in no way associated with the original outfit in Connecticut. Yeah, they bought the name, but that's all the relationship.
Second, they don't "make" a damn thing. Like most other brands they buy everything from outside suppliers. Last time I looked, their uppers and lowers were simply Conti pieces, and Continental makes the uppers and lowers for at least 5 other outfits; including their own subsidiary, Stag.
In other words, thgey're an assembly plant; not a manufacturer. Nothing wrong with that. Just about all ARs are put together in assembly plants. Just don't make the mistake of thinking you're getting something spedial with one brand or another. Almost all of them are putting out more or less good stuff these days; and almost all of them are putting out the occasional piece of junk.
Asking for input on a particular brand is pointless unless you're willing wait for a thousand or more replies. Just because one guy is thrilled w/his piece doesn't mean that you won't get today's production line POS when you order tomorrow. Sure some brands have a better overall reputation than others, and that's what you should be after. Not individual experiences.
