Sheridan Sights way off on Sheridan Blue Streak.

Can anyone explain why the sights are so far off?

I was given this Sheridan Blue Streak and noticed the aim was way off. I tried adjusting it with the screw on top of the rear sight, but even with all the travel it was still off. So I removed the screw and pushed the sight right out (see attached pictures). Now it shoots on target, but should the sights have to be adjusted this much?

Many thanks.

Congrats! That's a nice example. Post more photos, please.

Wow. That's a lot of adjustment! Have you examined the muzzle to see if something is off with it? I'd also look to make sure that there isn't any separation between the tube and barrel.

The rear site on that rifle was originally mounted about six inches forward of where it currently resides. That would have an effect on how much adjustment is needed.

Cheers,

Holley Genius""ya might try pulling back the bolt and shine a strong lite in the breach barrel and put the rifle on a bench and put the sight back in the middle .Put a piece of paper about 3 -6ft. away and see where the lite beam is as to where the point of aim is?the lite beam should eather be up or down where you have sighted afraid its going to be left or right?

Remove the sight insert you've adjusted. Hold a straight edge, or a piece of string, on the top of the front sight and bring it back to the center of the breech and compare it to the centerline of the barrel. There's a good chance the barrel or barrel/pump tube is bent. If the barrel only is bent it either left the factory like that or it separated from the tube and the solder/epoxy repair was bad.

I would have a look down the barrel, with a light in the breach, cocked, bolt open, no air , the view should be concentric all the way. Any bends will be easy to see.

Next, I would shoot some groups to confirm the barrel accuracy, irregardless of poi. Is it accurate?

Next, I would remove the sights anyway. They have been known to damage the barrel to compression tube solder joint. If you want to keep them, move them to the factory position.

That would also reduce the offset needed to correct for the right poi problem but I doubt that be enough.
You need the area just ahead of the breach for a proper grasp during pumping, so try to keep any sights out of that area.

Amazon has Sheridan intermounts for mounting optics, as well as inexpensive red dots. You could probably get both for $60 or so. Here is that sight setup on an H9A pistol.

I'm interested, so keep us informed.

A guy in Hawaii (eBay) is selling replacement clamp on sights for the Sheridan and Crosman pumpers for those of us who have removed the factory rear sight.
I bought one and mounted it to see how it fits.
Very nice but I don’t use it because I have a Williams peep on my Crosman/Sheridan Bluestreak.
(Note: I also have the original sights with the wedges but I cannot figure out how to put it on..)

Have you looked at the crown to see if there is one? Or if it's been knocked on one side. The barrel looks to be fairly straight in the picture, but that may be deceiving?

I don't know that he is reading these posts at the moment. I mentioned a simple accuracy test that would reveal a Crown problem. I have this same issue with a Crosman H9A pistol.
