Decided to build my first AR while it is still "legal" in Maryland
 Ended up sourcing majority of my parts from PSA, figured at least the PSA upper and lower should be a reasonable match. PSA billet 80% lower. I don't think it'll be too much of an issue machining out since I'm pretty handy in fabbing many things out of metal....No MSP wait here  PSA lower parts kit (flat dark earth). Includes Mil-Spec Magpul ACS-L Stock, MOE grip, MOE Trigger Guard, Palmetto State Armory Classic Lower Parts Kit and Mil-Spec diameter 6061 buffer tube assembly. I figure I can upgrade trigger parts later if I want PSA Hammer Forged Mid Upper - 14.7'' CHF CL Stripped Upper (with blem) - mid length gas system, F sight post Mil-spec carry handle Surefire flash hider/compensator (will pin on the barrel and cover the pin with my TIG welder) JoeBobOutfitters NiB BCG and charging handle Magpul MOE FDE handguard

finished "machining" the 80% lower today.
Used only a drill press. FCG pocket has some wave in the walls, but the FCG assembled fine and functions appropriately. Going to do the "homebrew" type II anodizing on it. I don't want to serialize it that is required by FFLs who do type III.

Thats a good build list. I like that your going from an 80% lower. I would was thinking about doing atleast 1 in the future but gotta find someone who can machine it.

Oh...for those that machine their own 80%. Be cognizant of the depth measurement. I was surprised how little I had to machine to get the trigger slot cut after cutting the pocket to 1.250
after a bit of research, I'm going with some KNS anti-rotation pins. This should help minimize any wear to the lower since it won't be hard anodized (type III) JoeBob NiB BCG arrived yesterday....what a work of art! The Surefire muzzle brake shipped yesterday. Want to make sure I permanently pin the brake on the barrel (TIG weld over the pin) the day the upper arrives. Don't want to get into NFA issues Guess I need to start finding some Ammo for it
