Before the Obama scare and Frankenstein Feinstien and Company scare you could get the parts from several places but right now there is not a lot out there at a reasonable price. I was talking to my buddy that is a LGS dealer here that is now one of the larger dealers in Oklahoma and he can't get anything. He sold over 200 ARs last week in various calibers except one--the Colt 901 he is holding for me. It i good to know a dealer before he is a dealer. In fact last week I started Christmas vacation on Wed. and worked for him on Wed afternoon through Sat. It was basically a down payment on the 901. Good thing I have a couple extra 20 rd Pmags sitting at home.............people are asking and getting a 200 bucks for them. There is not even a ban but people have gone insane. I can get by on 5 mags for now, or once I get the rifle. Hell I might even have enough other mags left over through the years to do some trading LOL.
