Joking aside and an eye roll to the "move to a different state" crowd....
If you're planning on mounting an optic, there is no need for an old school Front Sight Base, so no worry about the evil bayo lug.
Find an upper with a target crown or no threads on the barrel, they exist. Your neighbor at the range will also thank you.
Find a fixed stock. Can never go wrong with an A2 stock.
Grab some pre-ban 20 round mags, better for range use than 30s.
Toss in a good trigger while you're in there and enjoy!
