I have this mount from Midwest Ind. MOUNT
I have 5 Arsenals rifles and the mount lines up center of bore on all the rifles but the SGL 26 61. It sits more to the right of the bore, however it looks true just sits too the right. My question is if I put a scope on this rifle will the shots shift slightly as I shoot further out. I have taken dental floss from the front sight post to the end of the stock and the rifle and sights are straight. The side rail on this rifle is a slightly different style then the others. |

Line of sight is a straight line.
Your line on the barrel is also straight except in the vertical axis. So, if your line of sight is DIFFERENT than the line of travel of the bullet, yes. Aligning your sight will be hard to impossible depending in the offset. Everyone deals with the vertical difference by zeroing to what you like and then holding over or under. If your sight line is SIGNIFICANTLY offset, now you are trying ot zero to a point on that bullet trajectory from the side. This means you can only intercept that arc in one spot. If its small, not a big deal. If its a lot, now you have to deal with hold off in not only the vertical but also the horizontal depending on where you zero. ETA: this is the major problem with ANY side mount scope mount. Integral rails like the AR flattop can be almost assured to parallel with the bore line. Side mounts can be close. Integral mounts to solid receivers like the Mosin, '03, mauser and such are better because the mounts a machined to those specific dimensions. When you get into a stamped receiver, there may be a little twist to it or even variations in the stamping. This just adds variation to the way the scope mounts. Close up use, not much deviation. Longer shots (zero's), more deviation. |
