Dovetail To Weaver Base Canted

(1/1)

Bourdlay:
 I have a dovetail to picatiny rail with weaver 1" rings, the rail sits canted causing the scope to optically appear canted, but when you level the rifle and the scope, everything is square. When you take view the reticle appears canted relative to the barrel of the gun. It bothers me because, when I am off-hand shooting I shoulder the rifle and I have to adjust for the cant, shooting off a bench is no problem. I used the base because I have so many weaver style ring sets. The base I am using is an off-brand purchased on EBay for like $10. Are the $35-$50 bases going to solve this issue? Is the quality causing the base to mount on an angle?

Thanks

Bourdlay:
After I think about it, while experimenting with the rail and mounts, it’s pointless to have a weaver rail, on this gun (X10). Their is so much dovetail space that you can position your rings to compensate for eye relief, making the rail pointless. I think the notch on the barrel is going to fit one of the rings I have for eye relief positioning. Is it imperative that one of the rings go into this notch to prevent movement from recoil? Or can I position the rings outside of this notch and get them tight enough yet not cause damage, but also have no movement of the mounting hardware? I would still like to know if the cant is from a cheaply made base rail, or if a more reputable rail would not suffer from the same issue?

Man, that is a lot of questions.

Thanks

  Hey Bourdlay

  Dealt with this problem endlessly until i went to the  BKL brand mounts if i don't need a stop pin and i use the Hawke mounts if i need a stop pin,from Richard on this site, www.airscopes.com       both of these mounts center your scope properly, so long as the dovetail is cut straight, hope this helps,  Jeff

Bourdlay,
So the gun has a dovetail, and you have a one piece dovetail to Picatinny base, with 2 individual Picatinnay rings on top of it?  Is that right?

First question I am wondering is why can't you just rotate the scope in the ring mounts to level it to your liking?

If that isn't an acceptable fix, depending on how much time you want to spend, you can fix it with a file and sandpaper.

Here's the process:
Set the gun with mounted scope in a rest and level the GUN up to your liking.  Looking at everything from the rear, figure out exactly what is wrong.  Most likely, the clamp bar that engages the guns dovetail is either too short or too tall, tilting the base to one side.  Remove the clamp bar and flip it over so that the other pointed part fits into the dovetail on the gun.  Tighten the screws and check for tilt.  If that fixed it, great.   If not, you'll see that one side of the dovetail part of the mount is too tall.   All you have to do is shorten that side. 
Remove the mount form the gun.  Lay sandpaper or a file on a flat surface and carefully  file or sand the bottom of the leg that is too tall, being careful to maintain the original angles.  It's probably aluminum and should go fairly fast.  Keep filing or sanding until the fit is right.  You can use black magic marker to touch up the black anodize on the mount after you get it to fit right.

BTW, if a gun's (or mount's) dovetail is too wide or too narrow, that can throw some cant into the scope.

Bourdlay:
Cool thanks, I'll try filing or sanding to level, that makes sense. First I leveled the gun and clamped it in the gun rest. Than I placed the scope in the rings and leveled the scope. On the bench everything appears level, but offhand the scope appears canted due to the rest being on an angle. Being that the scope is level relative to the bore of the rifle, trajectory won't be affected, but shouldering the rifle the reticle appears canted because of the angle of the mount. This mount is cheap, I will just replace it with a one-piece quality mount to solve the issue.  Thanks for the input fellas.
