Sighting Problems on a late Inland

[Sunray]

"...250 yds. to make it hit POA..." At what distance?
It's the front sight, but you do not file that to lower the POI. Front sights get moved in the opposite direction you want the group to go. I'd be inclined to find a matched set if you can. Vs fiddling with the front blade.
Or you could just shoot it the way it is. Knowing where the thing shoots is most important.

Shooting it "the way it is" works, but I'm more interested in finding out why this carbine needs the rear sight set at 250 yds to hit where it's aimed. My shooting distance is 25 yards and I use the 25 Yard M1 Carbine Target from the TM when trying out a "new to me" carbine. The ammo I used is Remington 110g MC. What do you mean by finding a matched set? If you mean a set from another gun, you'd end up with (2) guns that need some "fiddling," wouldn't you? I doubt that both sights have been changed on this carbine, but one or the other may have been. If so, which one shows more evidence of it? By appearance, the rear one may have been swapped, or at least moved slightly to the left and then re-staked. The way it shoots points to the front sight being replaced, but why wouldn't it have been targeted? I'm still waiting for someone to comment on the "tool mark" shown on the left receiver rail. Thanks! - Bob

Bob none of your photos show the left side of the receiver.

On the top of the left rail, Bruce. Looks almost like a mark the jaws of a lathe chuck can leave on a work piece. Possibly from a fixture or vise used in the milling process?? I was also thinking it could have gotten there from tools used during a barrel change, or some other GI carbine tool such as for changing the rear sight. - Bob

I doubt that the sight was factory installed. There were six stake marks on this sight two of which are almost in two others The vast majority of factory punch marks are done on the right side and just two punch marks. But someone sure wanted to be sure this sight just did not have a chance to move.

Bruce, I agree about the rear sight staking on this carbine. Was it you that posted awhile back about the differences between Type 2 and Type 3 rear sights in regard to the area on them meant to be used for staking? It seems like it was in reference to information in a CCNL, but may have been something I read over on the CC Forum. Can you think of a reason why this carbine has nearly a full height front sight on it? Your earlier post sounded like you thought I needed to add height to it, but that would be going in the wrong direction. I have several other pictures of the front sight (different angles and lighting) I can post, if it would help. Thanks! - Bob

The rear sight could have been restaked at a later date, that would explain the divot patterns. Also, original sights were not always staked the way some newsletter, book or online site says they were. Securing the sight to the dovetail, adjustable or flip, was the most important thing.

[USGI]

There it is. I can't believe the discussion continues as if the question were not answered.

The actual question was not how to sight in a carbine, but how this carbine escaped getting sighted in. The sight doesn't appear to be a recent addition. I'll check the blade height, but it does appear to be close to "new" dimensions. It's not exactly what I would call a new sight, though! - Bob

how this carbine escaped getting sighted in.

I think the suggestion of it having a flip sight originally and then the adjustable one being fitted makes most sense. That would account for it. Why it wasn't re-patterned, well if it was fitted after the military, then that would do it. There's no way to tell if it was civilian fitted. At this age, it's just guessing...

Oops. Okay, I'd say it had the 'wrong' sight on it after the rebuild and somebody 'corrected' it but didn't bother to sight it in. Yes, I agree, its not really a 'new' sight because they have really high, pointed blades. This one has been adjusted but just not for the rifle its on now.
