Sweet! I have an upper/lower with a Geiselle NM match trigger, PRS stock and the same Lancer handguard sitting in my study, and was just researching the best 6mm cartridge for the AR15 platform. I had planned another 223 but have 4 already, and not a fan of the AR10 platform, just too big to me.

Seriously thinking about building a 243LBC VERY similar to yours! Was thinking 24" but seeing your pics has me questioning that.

Really appreciate the list of components, etc. Would love to hear any tips, advice, thoughts you might have in hindsight, etc.
