If I was going to add anything to my list it would be:
(2) Colt 6529 [AR-15A2 Government Carbines with 16" Lightweight Barrels and Fixed A2 Carry Handles].
I'm struggling with my decision to sell these two, because IM(not so)HO they are EVERYTHING an AR should be:
SUPER LIGHT (5.8 pounds)
SUPER ACCURATE (best sights ever placed on a military rifle ... I do slightly prefer the A1 for durability)
SUPER COMPACT (no rails, etc to clutter up a KISS carbine)
SUPER ACCURATE
These simply make uber handy KISS carbines. I ran 250rds thru one of my two 6520 (not 6920), and 200 each thru my two Scar 16 last weekend. The little Colt was just a joy compared to the 10 pound (once scope / accessories are mounted) FN.
