I mounted a Center Point scope on my new QB78S after and preceded to sight it in, which is usually only takes a few minutes, however not the case today. At about 10 yards it was shooting about 3 inches low and 2 inches to the left. Should have been an easy job, however no matter how much I adjusted the scope the group never moved, just clustered in the same location. Well after many tries I figured the scope was bad and took it off. Then I mounted a red dot sight and low and behold I had the same darn problem. So I begin to thing the gun must be at fault so I reinstalled the rear sights and made my first shot and I was only about an inch off vertical and about 1/2v inch off horz. Made a sight adjustment and it shot great and even did well on my reactive targets. Any idea what's going on? I guess to be sure its the scope is to try a different scope. Also had one other strange to me happened and that I had my first new CO2 cart without any gas. By then I figured it was time to stop and go watch some football. Charles
QB78S strange things happened!
- Thread starter sekiar
- Start date
It sounds (looks?) as if the barrel isn't mounted in perfect alignment with the receiver. Try loosening the allen grub-screw on the top of the receiver and the barrel band, then pushing the barrel to the right. Tighten both, then re-test. The o-rings on the barrel don't alway line things up as well as they might.
The sights are barrel-mounted, so the (potential) lack of alignment won't affect them.
I removed the barrel band on mine to get the best accuracy. It ended up looking like the very first model Crosman 160. Who knew?

P.S. - Roll Tide!

A great idea! I did as you suggested and when the weather improves I'll give it a try and see what happens. Charles

Will try to remember to do that. I too love the QB78 family and hope to order a QB repeater very soon. Also ordered Archer's manual on the QB78 series. CharlesThat's great news, Charles. Glad to be of help. These rifles are my favorite.
