i have thought about doing that as well! hahaha
I actually have done it......once. Guy was trading an 1895 45/70 that was built in the way back machine. Wanted a mini-14 for it. One of the cops I was working with at the time had a mini he was trying to sell to buy and AR. Gave him 350 for the mini, and swapped the mini for the 1895 30 minutes later.
