Figure I'd post this for anyone who likes to see a project from start to finish. I hope to not have much lag between updates, though I'm still debating on what components for the lower and getting loot together. I'll include pictures along the way, though I'll wait until the THR servers are all finished up. Here's a general outline for now. Feel free to discuss, ask questions, throw tomatoes, etc. Here's what I've got spec'd for the upper: Barrel: Pac-Nor 16" medium contour, polygonal bore, 5.56 chamber, extended feed ramps. Receiver: CMT mil-spec with extended feed ramps. Muzzle device(s): Smith Enterprises G6-A2 Vortex. Gas system: Mid-length, direct impengement, Vltor low-profile gas block. Handguard: LaRue 10". Iron sights: (BUIS) Troy battlesights. Bolt carrier group: LMT enhanced. Charging handle: PRI M84 Gas Buster. .
