    Scoping a Henry AR 7

    Looking to put together a pack with a detachable optic on my AR7. Anyone ever experiment with this ? Found this article, but am looking at more specifics on detachable rings and a pack for the outfit.

    Personally I would buy a Ruger TD 10-22 and forget the AR-7. I haven't touched mine in a couple years... Not since getting the Ruger. I have a Marlin papoose too... it also sits...

    Have you seen this site?

    They offer a ton of AR-& stuff you did not know you needed.

    Generally, Weaver style rings will consistently return an optic to the zero position if one side of each ring is non-adjustable (or stationary) by design.
    For example, Simmons rings that fit a Weaver base are inexpensive, one side remains stationary and they can be detached
    or re-attached with a coin since the screws have wide and deep slots.

    On the other hand, .22 tip-off rings for the 3/8's receiver dovetail can sometimes become lose and move due to recoil
    unless each side of the ring bases have independent tightening screws that create a tight grip such as Millet Angle-Loc rings have.
    However those can be much more difficult to return to zero after removal since they're windage adjustable.
    Once the tightening screws are loosened the windage adjustment can be lost along with the sighting-in zero.

    Tube style dot scopes with integral Weaver style bases or rings usually return to zero.
    The least reliable to return to zero are the reflex dot sights IMO.

    The main issue with any scope is that the higher it's mounted, the more critical the sighting-in distance becomes.
    You don't want to sight in the scope for too long of a distance or too short of a distance since 22LR bullets will drop at 100 yards.
    Below is a 22LR trajectory chart. But the actual trajectory can be a little skewed if the scope is mounted too high.
    But that's hard to overcome and won't matter too much if the barrel or ammo isn't super accurate at 100 yards anyway.
    Just try to learn where your gun's point of impact will be at different distances after you set it up and sight it in.
