Right after Sandy Hook the AR-15 magazines were crazy expensive. A relative who was in the military had given me a grocery sack full of worn out GI magazines many years ago and I sold them for 20 bucks a piece. Ammo was also very high and I went up in the attic and found many old boxes of .45 Long Colt and other caliber that were quite old. With the cash I collected I picked up a nice old 4" M66.
