Like getting 2 rifles for the price of one! Includes .177 caliber and .22 caliber barrels. Red fiber optic front sight and green rear fiber optic that are fully adjustable. The Beeman 4x32 scope will help get the most accuracy possible from the gun. Max velocity in .177 is 1000 fps, and in .22 it's 830 fps. You could use this rifle for plinking, small game hunting, shooting cans and just plain fun!
