$1000 plus a $170 tire pump May have to think about that one a little bit, unless the lottery comes my way.
You don't want to try keeping a big bore air rifle filled with a hand pump. I use a scuba tank and it's cheap, quick and easy.
This rifle has very similar ballistics to a 300 Blackout. It also has an incorporated silencer in the barrel shroud already, straight from Benjamin.
What would be the cost of a .300 Blackout, and then the suppressor and tax stamp? Probably a minimum of a couple grand?
Not to mention the waiting because of the "firearm & suppressor" factor.
Not for everyone, but it does offer some very nice alternatives.
