    Not really sure how to phrase the question, but here is the situation:

    A couple of years ago, I had a detatched retina in my right eye. While I can still see with it, it's not great. I can't use iron sights on my Mini-14 anymore.

    I can see a bit through a scope, but not sure how it will be in an actual shooting/hunting situation in the field.

    Trying to shoot left handed seems totally un-natural to me. I'm not sure that I will be able to shoot left handed.

    What I am wondering is, is there any device/scope that I could get that would allow me to shoot right handed using my left eye?

    One solution that I can picture is that of a small video camera that would attach to the rear of the scope and have a small monitor like you see on regular video cameras that swings out to the side where I could see it with my left eye while shooting right handed.

    The other possible solution is a prism device like a binocular that would offset the view through the scope to the left enough to see through it with the left eye.

    If anyone knows of a device that would help me out, I would be most gratefull!

    Thanks in advance.

    The problem you desribe has been "solved" in the past with cross-handed stocks - at least that is on shotguns however the gun looks a mess and it is still a compromise. Changing scope mounts on a rifle to push the scope far enough across to comfortably shoot right-handed and left-eyed is again a poor compromise which still isn't going to feel "right" until you get used to it. If you accept that why not continue to try and shoot left-handed ? I am right handed but shoot left as my left eye is dominant. This does make a lot of sense if you think about it since you strongest hand / arm will be holding the weight of the rifle while your weaker hand only has the trigger to pull. It took me some time to get used to this way of shooting but right-handed now feels "wrong" even though as I said, I am right-handed.
    Also for greater accurancy the scope needs to be as close to the barrel as possible lifting it to shoot left-eyed is a bad configuration.

    you can theroretically off set the scope as far as you want this doesnt effect accuracy. it does effect point of impact when you shoot shorter or greater distances than your zero. for deer hunting as in whitetail ranges are seldom past 200 yards. typical distance somewhere between 75 to 125 yards. a zeroed at 100yards offset scope will vary the impact right/left by about 1.5 inches at 200yds-ish.

    With just a little practice,you should be able to shoot left handed.It will feel very awkward at first,but it just takes a little time for your brain and body to adjust to it.
    I have always shot left handed-eye dominance thing-but I'm right handed.
    I can shoot right handed,but it took a little practice time for me to get used to it.I'm almost as good at shooting right handed as I am left handed.

    JonM: Very interesting solution. Thanks!

    I was thinking of something like this myself, but didn't know if the parts to do it were available. I was also concerned about the extra change in bullet impact due to the side offsetting. But realistically in a hunting situation, should not be that bif a deal.

    Thanks also to Photopro!

    Scope mount

    It looks like they're redoing their website right now but, RW Hart & Sons has an offset scope mount to do exactly as you need. Pictured below, the idea is similar to the rifle mount pictured in a post above. If you call or email they might be able to lead you to more photos/descriptions. It is in their printed catalog too.

    Just had my shoulder replaced and I guess it was a mess, doc told me from now on shoot left handed. he told me it woulld take a while but he did it so he said I could do it. I went out to the range a couple of weeks ago and set down at the bench to get use to it and if you give it a chance it will work. I realize you dont have a bench in the field but what I went out and got was a tripod for shooting like you see them using on the hunting shows, solved the problem right there. You can do it so dont give up on us we are behind you .

    I am right handed and also originally right eye dominant, but a industrial accident ruined my right eye. I agree with those who say learn to shoot left handed it has been the only practical and economical solution for me. Takes some time and practice, but it feels natural to me now. Ron...

    Just found an interesting article in Guns Magazine (April 2011 issue - page 24) that almost describes the solution I had posed here in my original post.


    The Camera Sight
    An innovative use of the simple camcorder.​


    I have never had an original thought in my life. And if I did,
    I wouldn’t know what to do with it. That is not a problem
    for Chris Self of Selma, Ala. He is not only an innovator, he
    has the ability to make his ideas reality.

    Some months ago I reported on a
    Variable Gantry Mount (VGM) built
    by Chris Self. Instead of using clicks
    on the riflescope or hashmarks for
    holdover, the base mount has a small
    handle that moves from one position
    to another. The positions are aligned
    by screws along the mount to which
    the small handle is moved. For a biggame
    rifle with a long-range, flatshooting
    cartridge, you might have
    10 positions, each sighted in at 100-
    yard increments out to 1,000 yards.
    Sliding the handle to the 10th position
    takes only a fraction of a second,
    and it doesn’t wear out the scope’s
    internals. It works! While that is only
    an example of the mount’s many uses,
    Chris has had great success with it
    on shooter’s competitive guns, highpowered
    pistols, thunderbooming
    rifles, you name it.

    Failing Eyes

    As it turns out, Mickey Coleman,
    a benchrest shooter, machinist and
    rifle builder, whose eyesight is failing,
    is a friend of Chris’. Another of
    Chris’ friends has developed macular
    degeneration, restricting his vision
    to just a few inches. Chris Self is an
    idea man and an innovative inventor.
    Give him a problem and he will not
    only solve it, but build it. His friends
    having problems seeing got Chris’
    brain churning on their plight.
    Chris and Mickey found a small,
    inexpensive video camera and set to
    work. They located the image center
    of the camera’s lens and then marked
    the spot on the screen with a small
    triangular piece of electrical tape.

    They worked out the details of
    the camera and mount for a test run.
    They discovered some interesting
    things along the way. The camera can
    be used to shoot around corners, as
    well as some fun shooting over their
    shoulder, the target being behind
    them. The possibilities seem endless
    and an inexpensive way for some
    people to resume hunting or simply to
    have loads of fun.

    The prototype that Chris sent me
    uses Chris’ VGM mount. He built
    a camera mount to fit on top of
    the VGM to hold the camera and
    that allows windage for sighting in.
    That gave him an expedient way to
    accomplish his test run. He is currently
    working on another mounting system.

    On A .308

    Chris and Mickey had been using
    the camera and mount on a .22 rifle
    and were astonished at the variety of
    things it would do. I wanted to see the
    effects of mounting it on something
    larger and chose one of my .308
    tactical rifles. Mounting the VGM on
    the Picatinny rail of the Nesika action
    took only seconds. I gathered up some
    Black Hills 175-grain match rounds
    and drove to the range. I stapled
    a 6" diameter bull on the backer,
    wondering as I did so if it would be
    difficult to sight the camera in. The
    small Sony Handicam is turned on by
    opening the screen. At lower powers,
    I could easily see where the camera
    was pointing, and I found the target
    immediately. The little camera has a
    60X optical zoom. At that power, the
    target was very defined.

    I removed the bolt and, looking
    though the barrel, found that when the
    triangular tape Chris had placed on
    the screen was on the target, the barrel
    was pointing about a foot to the left.
    Chris had provided windage screws
    on the mount, using them moved
    the camera to center over the rifle’s
    bore. Chris’ gantry mount provides
    elevation and both the camera and
    the bore were now on the target. The
    first 3-shot group was about 3/4"
    and low on the bull in the 5 o’clock
    position. That thoroughly amazed
    me. The rifle shoots BH 175-grain
    match rounds a little better than that,
    but even so that is with a high-power
    scope, a very fine crosshair and using
    a normal shooting technique. In this
    case I was using the top of Chris’ little
    piece of tape and my head above the
    rifle, looking at the screen!

    I readjusted the camera and shot
    another 3/4" group, this time a bit above
    the bull’s center. One more adjustment
    and the next round centered the bull.
    I sat there looking at the camera, the
    bullet hole in the bull’s center and
    thought about the possibilities of
    this system. The first, of course, was
    how this simple, inexpensive sighting
    system would allow many who have
    given up hunting because of failing
    eyesight, to once again put meat on
    the table with assurance.

    Only your imagination would
    restrict its use. The camera’s screen
    can be maneuvered 360 degrees. Think
    about the soldier wanting to keep his
    body behind a bunker out of direct fire
    but continue to place accurate rounds
    downrange. He could lay the weapon
    on the wall, tip the screen, and place
    the crosshair on the target and fire.
    He could, as well, fire around corners
    without exposing himself. He could
    have fun shooting steel plates over his
    shoulder, facing away from them—he
    could just have a lot of plain old fun.
    I moved the rifle and camera system
    to longer ranges and found I had no
    problem clearly seeing targets. With
    the Variable Gantry Mount, it would
    only be a matter of moving the little
    handle forward to each pre-sighted-in
    position and voilà!

    Chris thinks of his prototype
    as conceptual. He is working on
    providing a better aiming point,
    crosshair or something similar. He is
    thinking about hooking the system to
    a PC to which an integrated ballistics
    program could be used, and he is
    tinkering with a more useful mounting
    system. Knowing Chris, I am sure he
    will come up with all three.

    Chris and Mickey are trying to
    locate camera makers that might
    be able to incorporate a crosshair.
    The concept works very well, and
    the assumption is, the system will be
    relatively inexpensive and suited for
    sporting rifles.

    Chris has already made a few of
    these units available to sight-impaired
    individuals and a group that sponsors
    hunting for the handicapped.
    The unit will allow people to
    record their hunts, shots, whatever or
    take single pictures of them. Many
    cameras incorporate NVDs. Image
    stabilization might prove helpful.
    What are the effects of the camera on
    mirage? The concept brings up myriad
    questions and possible answers.
    While such systems have been
    introduced to the military and others,
    they are often priced above the
    average person’s income. What Chris
    and Mickey envision will be both
    affordable and useful. Chris says he
    will respond to the public to produce
    the mounts if there is a need. Give
    him a call or e-mail him through the
    website. I am willing to bet you will be
    as captivated by the usefulness of the
    system as I am.
