looks like a 102should have a tube along side the left side of barrel with a loading hole near the far enda spring cover slides around for closing the holethis gun is a gravity feedwhen you cock the bolt you will see the pellet loading gate slide left and rightthe pellets slide down the tube into the gate when you cock it with the boltthe gate slides over and presents a pellet when you close the bolti bet Google might show some good images somewhereif noti can get mine out of the safe tomorrow and take some picts showing it
