I modified the scope mount using a CVA muzzleloader mount. Had to do a bit of drilling and adjusting but now I can take those head shots on sparrows and rats so hard to do with open sights. I use predator pellets for single shot pest elimination and bbs for fun multi shot can popping.

actually it’s rifled. I thought the same thing till I saw inside the barrel. It shoots predators at around 400 to 415 fps. Not much, but it will do a number on pests with a head shot. it is accurate to around 15 to 20 feet.
