30 Carbine sight pic.

[Hayfield]

I've been playing with my Inland recently. Groups well enough with a 311359 and 11.5 grs IMR 4227. But it shoots about 1 1/2' high at 100. What are you guys doing with your sights to get a reasonable sight picture? Also, I've had to move my rear sight all the way left to line up 6 & 12 o'clock. That doesn't bug me as much as having some 'aim way low' sight pic.

Now, I'm gonna get some heat over this but the old Army armorers put the carbine barrels between a couple of posts and bent the barrels to more or less "zero" them in azimuth. It would work in elevation as well. The M1917 Enfields were done the same way.

I have a Standard Products and mine shot way high. My machinist buddy welded an extension on my front sight and I took a file to the range and with the sight sitting at the lowest position, I zeroed it at 25 yards by filing it down. That gave me plenty of elevation for distance shooting.

Those are two suggestions and I know the second method works./beagle

Beagle. I can get the weld done. How hard is it to take that fromt sight out so that I can get one to weld and put the original back in if the need should ever arise.

Concur with beagle on welding up the front sight, it's the best way. Front sight is not hard to remove; drift pin out, drift front sight off the front, don't loose the "key". Some are on tight and a little heat applied to the bottom and sides of the band helps. There is a lot of verticle dispersion when different .30 carbine loads are used. I'd suggest zeroing at 100 yards using the ammo or load you will use most often. File welded up front sight down until point of impact is just on top of front sight at your point of aim. Have the rear sight on 1/1.5 when zeroing.

Larry,

Do they make different height front sights like they do for an 03?

I really don't know whether they did or not. I've never seen any. I always weld them up, file them to shape and then file down to zero. Doesn't take much and once done is very satisfactory.

Larry,

Thanks...

John,

I put together a parts kit from a replacement barrel that was still sealed in the bag when I received it and used the military manual instructions to do so. I also used the military manual's instructions to zero the rifle.

The barrel came with a front sight and the instructions called for zeroing at 25 yards with a specific (and odd looking) target dimensions. The sight was a bit tall and the instructions said to file it down "as needed" to get the proper zero.

When firing with Winchester white box ball ammo, I found the sight to be pretty much dead on and the only filing I did was to level the sight up a bit, as the machining had left a slightly rough place on one side, making the sight "look" slightly cock-eyed.

Groups, as one with expect with a new barrel, were excellent, both at 25 and 100 yards. If anyone's carbine shoot shotgun groups at 100, replacing the barrel is certainly worthwhile. It can be done with a standard 5 inch vice, a good size adjustable wrench and a military style pull through reamer you can buy from Brownell's.

Regards,

Dave

It's not hard to remove the sight. The whole assembly comes off. You drift out the pin holding it on and then using a brass hammer or a piece of hardwood and a BFH, you drift the whole assembly forward. Some are so loose that they just slide off. A square "key" sits in a slot and the pin anchors the whole mess together.

To reinstall. Place key in slot and tap gently with a hammer to seat and drift sight assembly back on until the pin hole aligns with the slot in the key. Place pin back any you're done.

Once you get the sight heightened and back on, zero it by filing off the top at 25 yards with the sight sitting at the lowest position and take it home and dress it up and reblue./beagle

I have owned over 20 carbines in my life (none now) and never had one shoot that high. either someone filed the sight down or the barrel is bent. I had one that ran out of windage trying to get it zeroed. I took it to my gas gun specialist gunsmith buddy and he found that the barrel was bent. A couple of blows with a lead no bounce hammer and my gun was zeroed again.

Bending barrels rings a bell. That reminds me of the WW2 street fighting stories in Europe where they used curved barrels to shoot around corners in house to house fighting. Elevation? What that?...Geo

Dug out the TM (TM9-1005-210-12) and the FM (FM 23-7, dtd January 1952) to see if they had anything on front sight adjustment. The TM did not and the reciever, barrel group are acoutable items and come with the front sight assembly. The FM did give instructions for "adjusting the front sight if the carbine hit low. I imagine numerous M1 carbines were thus adjusted but when they were put into different stocks the zero changed. I know that pressure at the front of the action so when the barrel is pressed down into the stock can cause lower point of impact. It is thus very possible that yours, and the few I've welded up among all the others have had thier front sight filed down per the FM. Attached are the pertinant pages from the FM.

I guess it's time to take the gun apart and check the barrel. The front sight appears to be untouched and reasonably centered in the wings. I'll start looking at some others and take some measurments to compare before I do anything. I wonder where on the barrel he used the impact adjusting tool?
