Gamo Model Delta Air Rifles
I bought these two air rifles for two of my young nephews. The one with the scope is a 17 and the one below it is a 22. Notice that the 17 has a corrugated recoil pad, while the 22 has a thinner, solid recoil pad, with a green spacer. Both rifles were tested with all the pellets we could fine, using a Leupold 2-7 Rimfire scope, at 50 feet. All groups are 5 shots from the bench. Of note, the MILBRO pellets were absolutely awful. they varried in size so much, some of them are almost running loose in the barrel, while others were quite hard to insert. Their weight also had more variation than any of the other pellets. To check the weight variation, we took 10 pellets at random and weighed them.
