Interesting idea fren, I don't have an AR so I'd have to start from the bottom but as a side benefit of the project that would justify some of the expense. Which looks like triple going by AA's proces (Garrow is down) but I expect similar, say $2k when its all said and done. If one were to shop for a matching target lower what are some good leads?
As far as ergo is concerned I'm not sure an AR really tops the charts there, in fact that humongous receiver is part of why I don't have one. The Savage has that trigger I'm just itching to try, and I'd be curious which platform can accomodate the lightest trigger. I've shot two that were a claimed "2lb trigger", they both felt closer to 50 oz. They weren't bad and they fit the platform, but I'd like to have a little more room if that was the bottom end.
But yeah, thanks Fren and fuck you very much for now expanding my short list of candidates
