AR key parts to buy pre-ban
If I wanted to attempt an AR build post-ban (assuming one is coming, hopefully not), what parts should I concentrate on buying now? I don't want to pay frenzy prices for a complete, but I may be willing to pay marked up prices for a few components, hopefully not many. Which would those be?
My guess would be the lower receiver and magazines. The other parts outlawed in the '94 ban as I recall were collapsible stocks and "the shoulder thing that goes up", but not separately or am I wrong about that? Anything else?
Thanks for the help!
