    I agree that it is most likely due to using the large aperture. The next time you go shooting try using both apertures for comparison.

    What he said. Ammo is not the issue here, nor is it the aperture.

    It's also possible the sights and/or the barrel nut is loose
    It would take a hell of a lot of pressure to get that kind of shift at 50 yards.

    Good call on the aperture QuietShooter.

    The only time it is useful is at night (and I haven't used it to shoot at night since I was issued an A2)

    The larger diameter sight, as far as I was told, was for night shooting with irons. And I'd bet dollars to donuts it's a combo of sight, shooter error. Also what's the dimensions on the target?

    .

    I'd think you'd have something obviously wrong to shoot that bad at that range.

    Like MistWolf said, barrel or sights loose? Whatever, something apears to be loose?

    FWIW, a 6920 I bought last year had an extremely loose Buffer Tube, like not even finger tight. Maybe your 6920 was put together the same day?

    But maybe it's just me....

    Switch to the small aperture. If that doesn't work then I would check the barrel. The obvious question is have you ever been able to get it to shoot a decent group?

    My guess would be a combination of using the large aperture, inconsistent fundementals (not as likely as your grouping with the 03 shows different) and a hardware issue. None of it can be confirmed without observing in person.

    Agreed, tow strap tight(and jacket) on a 20 g profile barrel will deflect 3-5"(low left) at 100, one would need much more on the 6920 to do this at 50.

    This was the first time shooting the Colt after a field strip and good cleaning. Nothing appears to be loose on the gun, and no, I have never been able to consistently get good groups at 50 yards with it.

    Yes, right hand shooter, left hand not on gun at all.

    The red center of the target is 2-inches. The outer circle is 6-inches.

    After reading most of the replies yesterday, I grabbed everything and headed for the range. I set up exactly as I did before. This time I used M193. I took 5 shots thru the large aperture. I wouldn’t call them a group, but the spread was smaller than the target I posted at the beginning of this thread. I then put up a fresh target, switched to the small aperture and took 5 more shots. Nothing on the paper at all. So I took 5 more shots. Nothing on the paper at all. I have no idea where those bullets went. I then switched back to the large aperture and took 5 more shots and got the group and one flyer in the photo below, which for me, I consider pretty good with iron sights at 50 yards.



    I always figured it was me, and not the gun, but now I’m beginning to wonder.
