    Rifle Scopes How Critical Is Sight Base Alignment With Bore?

    Re: How Critical Is Sight Base Alignment With Bore? There is shift in vertical position on each mount I checked. I remain convinced that evidence seen when scopes were removed from LaRue risers and installed on their respective AR-10 rails w/o risers shows significant offset of scope from...

    Rifle Scopes How Critical Is Sight Base Alignment With Bore?

    Rifle Scopes How Critical Is Sight Base Alignment With Bore?

    Re: How Critical Is Sight Base Alignment With Bore? Frank, Sorry for misunderstanding about the thousandth, ten-thousandth thing. What I am concerned with is not the dialed-in windage of the scope, it is the off-centered mount. If the mount is one-hundredth to right of the bore, the...

    Rifle Scopes How Critical Is Sight Base Alignment With Bore?

    Re: How Critical Is Sight Base Alignment With Bore? Scope that is positioned off-axis in amount that equals 8" at 100yds can, likely will induce tracking errors or limit vertical tracking at bottom range of movement (most distant range). Scope only tracks full 60moa elevation range of...

    Rifle Scopes How Critical Is Sight Base Alignment With Bore?

    Two weeks ago I decided to remount a couple of scopes had mounted on AR-rifles. Switched two scopes from bolt rifles to the AR-10s.
