It was a 22 co2 pistol from crosman, cut down a 177 Maximus barrel for it which shoots better than it did at full length which is very well. Made the stock shorter and made a bolt handle for it plus a threaded piece for the barrel for silencers. Put a red dot on it for him. He’s only five but got 6 squirrels on our last morning hunt and 1 was at 31 yds and one at 25. I have a picture but I don’t like to put them on the internet and have not yet learned how to black out faces
