There is a gun show coming up. I want to get started on building an AR-15 and know very little, however thanks to this site I do have a leg up. Basically, I plan to leave with a stripped lower reciever, but if the prices are right who knows what I may end up leaving with. How should I approach this? I will not spend more than $700 no matter what. I told the mrs that I would cool off on buying guns, but she was kind enough to inform me about the upcoming gun show. Is this a trick?.. JK Im not planning on getting anything more than a stripped lower but am looking for input on other things I should be looking for if the prices are right. Id just like to add that the primary purpose for this rifle is going to be a plinker. Im not looking for 1" group at 500 yards. I just want to get started into the AR-15 format.
