Sort of exploring options here. All I see is talk of either open sights or scopes on air rifles. What about a red dot. Do they work on an air rifle. I have an extra I took off of my pcc I use in shooting action games and I wonder if it will work. I just got my Gamo swarm fusion. I want to shoot the open sights a little first although the front fiber optic is way too small to see well. (That brings up another question about changing it to a bigger fiber diameter like in my firearms). The red dot is designed to go on a picatinny rail though, so are adapters made to change the mount on the Gamo to a pic rail?
