    You seem to be rather new to shooting in general. First, the bullet path describes a ballistic trajectory, so it will be at different heights along that trajectory, so it may not strike the bulls eye at both 50 yds and 100 yds. Second, any wind blowing at the range will certainly affect the carbine bullet, particularly over 100 yds. Third, what is a 'right front sight'? The rear sight looks okay. It is normal to have the sight base drifted a little to one side or another to correct aiming, and the aperture should be near the center position when the gun is sighted in, and it is. The thing that is wrong is, you never use the elevation adjustment of the aperture except to set it for longer ranges. Elevation is corrected as stated above by adjusting the front sight. Before making this permanent adjustment, you should have everything else repaired to acceptable condition/function (if the front sight blade is bent, replace the sight), and you should use the best ammo you can get for sighting in. Winchester .30 Carbine is about as good as it gets. Once you get to that point, fire at the 25 yard target with the rear sight on '1'. Lower the front sight blade until all shots are at or slightly above the point of aim, none lower. Then shoot at 100 yds. All shots should be above the POA, about 6" is normal. Notice that the rear sight lowest position is marked '1 - 1.5', meaning it is used out to about 150 yards. The carbine was designed to use the '6:00 hold' so the sight post does not obstruct the target. This means generally that the trajectory carries the bullet above the sightline except for the near and far zeroes for each rear sight setting.

    I have noticed that a lot of carbines

    when viewed from the rear well above the sights, show lots of off center things. My good Winchester has some off center on the barrel probably from a poorly done index mark or who knows. The fact that it shoots dead on is what matters. Point being; if the Type 2 sight was added later and requires an off set in the aperture to shoot, I wouldn't worry too much about it. The fact is that it shoots to point of aim is what is important. If you have adjustment remaining after centering, I would think that this would be a perfectly usable weapon to the Army. My NPM does not have as much misalignment with the original IBM barrel, maybe better quality, maybe luck?

    No, I'm not new to shooting. I've been shooting for a long time. However, I know sometimes I may sound a little ignorant, if I'm not getting my point across properly. And I have found this carbine to be more frustrating and have shot it less than other weapons. But I would think the fact that I knew what my carbine was doing at 300 must mean something. I'm betting a lot of people never shoot past 100.

    I thought I've been clear a few times about the front sight. If you see in my post earlier, I stated that to me it looks like the front sight is canted a bit off center, to the right. Which would definitely make it hit left. But what seems odd about that is in order to zero at 50 (which is what I usually zero my rifles at) my REAR sight is off to the left. Which in my thinking, is kind of opposite of what I would suspect, since the front sight is canted to the right. I would think that the REAR sight would be more to the RIGHT in order to correct the front sight being somewhat to the right. I'll post a pic of that. As far as it hitting to the left at 300, yeah, I suppose that could've been wind drift. But it was pretty significant. I own 2 AR's and a Loaded M1Aicon and I don't have these problems with it. Nor does my Garand or my 03A3. I've shot my O3A3 all the way to 600 with the irons and was on paper. I wasn't driving tacks or anything, but the point is I know how to shoot to some degree. Maybe not as well as you. But again, for some reason this particular weapon has had me scratching my head.

    Furthermore, no other weapon I have has been as hard to make run well, which I posted a thread about earlier. My Garand had some teething problems, but once I smoothed them out, it's been 100%. If this one wasn't particularly dogging me, I wouldn't be on here asking questions about it.

    Another thing about POI being 6" above the post. Is that something that is official? I have always zeroed my rifles with the POI being the top of the post. I like my pistols to do the same, although they don't always agree with me. Some of them seem to "shoot to the dot". Meaning lower down on the post. I don't really like that. But I don't really like a 6 O Clock hold / POI either. It seems very vague to me. And I don't think I'm the only one who is in that camp. I have discussed this with others. Now, if the carbine was "designed" to have a 6 O clock POI, I guess I'm in the wrong. But I don't zero my Garand that way or any other rifle. And you don't have to. My garand is about 7 clicks up, if my memory serves me correctly, to zero at 100 and from what I understand, that's AOK.
