I think, this is hard to bore sight, because it's tilting barrel and the scopemount isn't on the barrel, but over the 'chamber'.
I don't know, how the laser thingy works, but I could probably eyeball the bore and the sight enough to bring this closer to center, without test-shooting it...
...if it was a different lock up design...
I could do it with a tilting barrel gun, when the scope (or any sight) is fixed to the barrel and tilted with it....
hope that makes sense.
Expensive equipment is totally wasted on an old old old cheap air rifle :D
I'll just adjust and shoot until the point of impact matches the point of aim well enough.. This is just for practice and fun anyways.
Sorry for the delay, a boresight rests inside the barrel of your gun and shoots a laser to the target. Makes it very easy to dial in your scope.
I bought mine on amazon, they are usually pretty cheap.
but that won't fit inside the breach and the scope isn't mounted on the barrel...
I'll look into it laters, thx!
also: this is 4.76 mm or .117 bore...
