Great package for the price
I purchased 3 of these packs for my father in law and I to build a couple AR’s together and they work great. Everything went together smooth quick and easy no excessive pounding or pressure to get things to fit. If you’re just getting started this is a great pack to buy along with a stripped lower and you’re good to go.
