If you want to roll your own, my two cents:
Aero lower, Aero no fcg lower parts kit with included Magpul MOE trigger guard and grip, and Aero carbine buffer kit;
Magpul MOE stock;
Rise Armament drop in trigger;
Spikes Tactical gas block and tube;
Ballistic Advantage or Faxon 16" 7 or 8 twist barrel, whichever is on sale the cheapest;
AT3 Tactical Spear upper and handguard combo;
Combat Armory generic charging handle;
KM Tactical bcg.
Should be right at 650 bucks. Spend an extra 25 and get a possibly better quality bcg at Right to Bear. Should be a good solid rifle either way. Save up for optic of your choice and mount, and an ASC stainless steel mag. Add a cheap flash hider or thread protector from whoever has them for ten bucks or less.
Solid Advice.
