It looks to be a .177 caliber air rifle. As such any .177 caliber pellet will fire in this gun... However, every rifle is different as to "what it likes", and you will find that some .177 caliber pellets are more accurate than others... Were I to buy this gun I would also buy one of the ".177 caliber Pellet assortments", or ".177 caliber Pellet samplers". These offer an assortment of various types and weights of pellets in .177 caliber, so that you can try them to find which shoots best in your rifle... But, any .177 caliber pellet will work in this gun.
