It was the Big 5 in Huntington Beach CA on Beach Blvd. It was the non-threaded barrel commiefornia version so I had to pay a smith $30 to thread it for me. I got it in early 2010 so the coupon I used is long expired. When they come out they are only good for one weekend at a time sorta deal. Just keep an eye out, type "big 5 bloody decks coupon" in google and you can find them and print them out.
The one I used looked just like this but didnt say excludes firearms in the fine print like this one says...mabe Big 5 wised up and doesnt let you use them for guns anymore.
