So I have two stripped lowers one mil spec and the other a light weight MAG TACTICAL.
I've been wanting to build a Mil Specish gun and was looking at the BCM EAG upper with FSB because I want a carbine with an FSB.
OR Build a light weight gun with BCM KMR LW upper
OR build a replica of M16A4 with ACOG and KAC RAS that I used in the corps and buy a Colt AR15A4. I know this kind of a pointless question because it is up to me but I thought I would ask I'm in a pickle. What would you guys do?

As of now I only have one complete AR that is 14.5 bbl and all the goodies.
