My son is running pretty much a whole palmetto build minus a lower he had and an RRA 2 stage trigger. I wouldn't hesitate to own one.

This kit has Magpul furniture and has everything but a lower I think... It shows a charging handle in the pic, but it isn't listed. So... I would verify before going that route. There's usually always guys on the Colorado Gun Trader facebook page that have lowers well under $100 as well. That would save you some on transfer fees.

AR prices are in the toilet right now so I'd check armslist as well and maybe you can find a good deal on a safe queen.
