I didn't buy much firearms stuff in 2010, I had another hobby consuming most of my time and money.
I did make one favorable transaction right before the end of the year though..
I had a DPMS AR that I was into for just under $600.
I traded that for a Saiga 12 and $300.
The Saiga 12 came with three 5rd mags, and two original Izhmash 8rd mags. I sold the two 8rd mags for around $115 each.
I made out well on that, I've got plenty more ARs and the Saiga 12 is a keeper.
My best purchase was a federal TID number!! Bobcat Steel, LLC was born!!
Close second was 1200 primers I bought on the side of the road from some crazy haired guy. That guy started a business shortly thereafter and now I have a great friend in Andrew @ Profire Arms and Supply.
I purchased a Glock 26 from hoosierfishing last December. Great gun with a price I couln't resist. Thanks again! I wouldn't buy another brand new gun if every future used gun purchase was just as rewarding.
