    m1 carbine

    shoots very high at 50 - 100 yards. Does any one make a taller front sight?

    Maxim, you might try this site to locate your manufacturer. It may not be a sighting issue but the fit of the stock around the barrel and pressure points, but that's to be explored. Does it do this from the first shot, or after the barrel heats up from a string of shots? Has the gun been modified? Is it a military weapon or a reproduction? How does it group otherwise?

    Military 1944 Inland. Very accurate, but shoots about 4" high at 100 meters which, reading about it was factorysighted for 200 meters. Could build up the sight with something, but would look bad. With 6 million of them out there, somebody must have the same problem as me.

    Give it an hour or two. Someone on the board will have an answer. My first thoughts were that it could be a problem with the sight itself. Not adjusted right or out of alignment. The other would be a pressure point on the stock making something worse.

    Re: m1 carbine

    Thanks for the response--actually, depending on the multiple places they were made, books say they were sighted for 200-300 meters. Works out about like I see---110g @ 2000fps sighted for 200-300 meters would be 4-5" high at 100. Must be a taller front sight out there . Rear sight down all the way. Sweet little carbine. Read for jungle fighting a favorite of Marines, and the M2 version for SF in Nam. Probably the finest sub-machine gun ever made.

    Maybe sometime during the gun's service someone filed down the front sight, or it's an unusually short one. If you put here the size of the post to compare it there might be an answer.

    Re: m1 carbine

    Is the rear sight fixed or adjustable, and is it dovetailed into the receiver? An adjustable original issue M-1 carbine rear sight is still available that is adjustable from 100-300 yards.
    Here's one source for it:

    Re: m1 carbine

    Nobody I'm aware of makes a taller front sight for the M-1 carbine. It's an integral part of the front sight ring. A gunsmith could add material to the top of the front sight to make it shoot lower, but you'd end up having to file it down to get it shooting where you want it.

    You could always just epoxy a fiberoptic rod to the top of the front sight. The sight radius is so short on an M-1 carbine that a 1/16" or 3/32" fiberoptic rod would probably raise the front sight enough to lower the impact point sufficiently at 100 yards. If you don't want the bright bead, just contour the fiberoptic rod to the sight with a fingernail emery board, and coat it with a black magic marker.

    Another option is one of these scope mounts:

    Remove the rear sight and install the base, and put a low power scope on it.

    excellent idea for fiber optic glued to raise front sight. Is there a blade thickness for the fiber optic diameter?

    The thing about fiber optic rods is that they are plastic. If you get one that is too wide, it's not a problem. Once it is firmly epoxied to the sight blade, it can easily be contoured to the correct width and height with a fingernail emery board.
