The front sight on my CMP Inland M1 Carbine has one of the leaves bent. They definitely do not line up. The problem is I don't know which one is incorrect in order to attempt a repair. Does anyone have info or measurements I can use to figure out what is wrong. Any help is greatly appreciated.

Thanx

A different approach

Since there don't appear to be any technical drawings available on-line I would appreciate someone with a pair of calipers and an M1 Carbine giving me a measurement of the outside dimension of the leaves at the top. I can use this to work off the centerline of mine and make an adjustment that way.

Thanx.
 
The front post is 0.078" wide =/- a few 1000ths.

From the left side of the post to the outside of the right guard is 0.408"

From the right side of the post to the outside of the left guard is 0.390"

It was easier to measure from side to side rather than trying to hold the caliper in the center of the post, so just divide the post width by two and subtract that from either other measurements.

Here's a picture of the front view of the front sight on my Inland carbine. As stated the post is .078 in. the width of the ears measured from the outside at the top is .718 in. When measured from each side of the post to the top of the hole in each ear it is .225 in. Hope that helps you some.

JediJJJ: Pardon me for a momentary change in the topic.

I know almost nothing about guns, having inherited a grandfather's very old .22 bolt-action Savage many years ago and used it several times over the years. Unfortunately he had already given away or sold his Carbine before he died in the late '70s.

But I bought an Auto Ordnance M-1 Carbine two weeks ago and have so much to learn (!). Compared to the old .22 it certainly is powerful and fun.

Both days I've used it this week, after loading about six rounds in the magazine, in order to not run out of ammo too quickly, a round jams almost each time-whether the first to feed or later- and it is always perched there at the same angle, with the copper bullet tip just below the chamber. :confused:I chamber the round fairly quickly, as recommended by the gunsmith.
The gun was lubed/oil at the gun store this week and appears quite clean. I never put it down on the ground, just onto a thick camouflage net on the grass etc. It was oiled just after the last time.

A hunter I chatted briefly with suggested oiling the magazine might help, and another said that when breaking in a gun, soft lead bullets help to "grease" the chamber. The two gun stores I've been to here only sell the Remington copper-jacketed ammo for the M-1 Carbine. Might another gun store here have a box of soft lead Carbine ammo?

What would you or anybody else suggest, or is there another related topic on this forum elsewhere?
 
All those things about lubing the mag and stuff is bologna saugage. You may have to do a little polishing and a slight recontour on the ramp to the chamber. As it is basically a pistol round fixes for this type of problem for a pistol may apply. Remember I posted a reply to you previously about what type of jam you were getting but you never replied. Also could be a concern with the spring that returns the bolt to the closed position not being up to par. Being it is a new firearm have you tried contacting the Auto Ordnance folks and see what they have to say?
 
IO, do you have just the one magazine? Is it GI?

GI carbine magazines are still inexpensive and you can still find them in their wrappers at gun shows. Buy a couple and see if this fixes the problem. You shouldn't have to oil the magazine beyond wiping it down and keeping it clean. You shouldn't have to use hunting ammo.
 
Lencac and Cuervo, thanks for the responses. Between them I think we'll have enough info to get this fixed. My Dad is a retired tool and die maker so he really enjoys working on this kind of stuff. I considered getting a replacement sight, but wanted to see what we could do first.

Thanx

Lencac and Gang:

Thanks for the ideas, and pardon my mis-reading or missing responses elsewhere. Was probably in a hurry.

Will try to find the phone number for AutoOrdnance, and try this larger (30 r.) magazine. It feels like it is the smoother magazine when pushing down on the ramp/'plate'.
