I went to EBN and got some new screws for the rifle scope. I installed them on the scope and rifle yesterday afternoon. I added the Permatex Blue Medium thread lock liquid to the screws this time. Hopefully this will keep the rifle scope locked in place. I even put the blue liquid on the scope stop screw once I got that scope stop in place. I was thinking about using some **** JB Weld in the hole where the scope stop pin fits to secure the pin in the hole better. The hole in the top of the rifle barrel is too shallow and the pin won't go down into the barrel's hole very far and keep jumping out when I shoot the rifle. The rifle is ERT but it's still got a very powerful kick that the scope stop thing can't really handle.

I'll try to sight this rifle scope in one more time and then report back on my findings. So far I'm just keeping my fingers crossed.

The new screws have a hex head on them and I used one of my metric 3 mm hex wrenchs to tighten them up. But they seem to be shorter than the ones that I had that were #15 torx heads. Some of the srcrews are longer than the others.

I contacted GAMO by email and they said that they can't tell me the size of the screws used on the rifle as they change monthly and yearly in size, head, thread pitch. I said that I would keep that in mind the next time I want to buy something from Gamo USA.

My only satisfaction is coming from the fact that I took the screws to Evansville Bolt and Nut Supply at 1701 E Columbia Street and they were able to match the threads and size and gave me ten new screws for free.

So I hope that the money I spent on the air rifle and the new scope are not wasted and these new screws help hold the rifle scope in place.

I can't keep and use an air gun who's groups are more than 12" apart. You can't kill anything with a guy that shoots that badly.

PS: I'm told that the slots on the rifle barrel are a Weaver Type scope mounting groove. They are 3/8" inch wide.
