I have found that GRABAGUN.COM keeps moving their firearm prices all over the place. For instance, the AR-556 is currently being sold (out of stock) for $607.01. I have seen GAG's price on it at $659, $626, $611, and what I paid for it, $599. I keep a log book of website prices on certain firearms. Why? Because I am at home most of the time and friends and family call me for the best price and where, for certain firearms.
Some of you might remember me talking about how small the town I live in with only 1 LGS within 50-60 miles. I also stated how he was price gouging on his AR's. I was in there yesterday to look around and he has 2 Sport 2's priced at $699! He has 1 Ruger AR-556 priced at $707!
The owner asked me (he does this every time I visit his store) again if I am ready to sell him my Sport 1. It has the 1:8 5R Melonite treated barrel. And as usual, I tell him no.
BTW, my best friend and I traded back rifles so I now have my Sport 1 again. It's a very long and very interesting story.
