M1 Carbine Sight look crooked...

I was peeking thru a sight on an M1 Carbine today. It appeared as thought the front sight was a few degree's off. I was told that it was the upper handguard giving it that illusion because it was an uneven plane to look down on that particular rifle.

What do you guys think?

If I'm wrong please correct me, I won't be offended.

    Lee: after reading your post, I took a USGI M1 Carbine from my safe and looked through the sights. There is no discernable line-of-sight distorton; the front sight blade appears true (90 degrees to the horizontal axis). I have had a couple of other M1 Carbines in the past, and never noticed any allignment problems with the front sight blades. Why don't you simply remove the handguard from the rifle in question, and look down the sight plane?

    Seamus' suggestion is good.

    If it still looks "off", the problem is most likely that the barrel was not correctly indexed to the receiver. This will require a trip to the armorer, since either the receiver threads are damaged, or the barrel is defective.

    You didn't indicate the maker of the receiver or barrel, or if the carbine was assembled by an arsenal or in someone's basement. There are many defective commercial or USGI-reject barrels out there.

    I think I would see how the carbine shoots, it may be like that for a reason. Good Luck.

    You could take the stock off and measure if the flat on the bottom of the barrel is parallel to the receiver bottom surface and adjust the barrel accordingly. The receiver can be held in a smooth jaw vise above the operating spring housing and the barrel adjusted with a large Crescent wrench.

    Hey thanks. I don't really remember who the mfg was. I'm going to go take another look at it. Its supposed to be original military. It has the old US bomb crest on the stock if that helps any. I don't really know a whole lot about M1 Carbines. I'm considering selling a few pieces and getting one for a local 3-gun match that is shot around here.

    If I'm wrong please correct me, I won't be offended.
