Amazon BSA R10 MK2 .177 -$710.23

"Cliff_Allen"Awesome deal, it was down to something like $675 a few days ago, that's the flat out cheapest I've ever seen it. At these prices I'm not sure there is a better gun for the money, or even a little more money. I concur, the BSA is one of my favorite guns as well.
According to the tracker it was down as low as $622. Shame they only have righty stocks

The gun will most likely arrive empty. Most air rifle cylinders are tested then drained before shipping. I did receive air in my impact which was a first. Pumping the BSA will be a workout, but can be very manageable if you stay on top of your air consumption. Like stated above, make friends with a paintball shop or dive shop and see what they can fill and gauge for a scuba or SCBA when budget allows.
