In the name of God, with God's blessing. I bought a binoculars with its bases. It's small and doesn't fit on the .22LR, but it's good for gas-powered and air-powered rifles up to 45 caliber. Anything higher will change due to recoil :::: Calibrated to 13 meters with an air rifle: Everything is clear in the pictures 🏅 There's a slight wobble on top for a short period🏅
