Inexpensive AR-15 Pistol

I built this AR pistol for less than $500. This was a virgin stripped lower receiver I bought awhile back and had never gotten around to building. So when I got the itch to build an AR-15 pistol, this was the perfect lower to build it on since this lower has never been built into a rifle. Check your local and state laws before you do this, but according to federal law and the laws of my state, this is legal. I had a full-length buffer, spring and tube that wasn't being used. The stock attachment threads were stripped, so I bored out the threads and used it. Cheaper and more reliable than the short pistol tubes.
