I don't know which state you're in or the detail of the ban, but it's a good idea to buy a bunch of stripped lowers just in case. For a complete lower parts kit, get any of the PSA kits that comes with a 2-Stage Schmid trigger, like this one for example. If you want to piece together your own parts: CMMG is a good option for the small parts, KAK is a good option for buffer components, Schmid 2-stage triggers are great, and I am personally fond of B5 Bravo stocks and BCM Mod3 grips but furniture is kind of personal preference. My standard recommendations for lower build tools are: $50 Magpul Bev Block - This serves as a lower receiver vice block as well as an upper receiver rod $15 Harbor Freight Pittsburgh 1/2" Torque Wrench $15 BCM KMR Wrench - Works for castle nuts as well as some barrel nuts $20 Punch set - Many options on Amazon but I've linked a pretty complete set + a vise if you don't have one
