Hmmmm, doom spending money; count me in!
Makasi:
-an LPVO,
-an extended front handguard,
-a pronged flash hider (preferably 3 prong, but 4 if I can't find a 3 prong)
-more Stanag mags, 'cause...doom spending, why not?
-case (or more) of M193.
-45 degree canted BUIS
I have to get the rifle in hand before I make any comments or commitments in regard to the butt stock, but I'll probably favour a fixed, propper LOP solid butt stock.
