Beeman dual..double barral air rifle

[Rocket launcher]

This is a reinvention if the air rifle
Called a beeman 2016 db with a .177 and a .22 barrel

What I find remarkable the barrals are over under but the pellets don't land above each other..
Then if you use heavy and light pellets
What a gun for testing pellets the results could be amazing
How do you sight your scope
It has a switch you can fire one barral if you wish or both.but as it's a springer will hardly be a fast second shot
