Krag carbine front sight

I have a US Krag carbine. Its previous life was a rifle. Someone cut 8" off its barrel, and put a 1903 type of front sight on its muzzle. It looks alright, except when I test fired it.

The front sight is way too tall, so it shoots way low, unless I set the rear sight to 600yd, the tallest setting before having to use the ladder sight. Theoretically I can keep on shooting the carbine like that, but it is rather undesirable for a few reasons.

I looked it up briefly. Sounds like it was a common method to convert a rifle to carbine. So I'm not the only one who has this sight issue. What's the proper way to put the rear sight to proper settings? I can certainly file the front sight blade down. But it is going to be as much as 0.2". When it is done there will hardly any blade left. Shimming the rear sight up is possible, but hard to do. It requires longer screws that cost a small fortune.

Your suggestions are much appreciated.

Easiest way would be to modify your handloads. I use a 190 gr lead bullet with an easy load of Tin Star for my cas clubs BAM shoots. I dropped a rd at a match one time so the RO [a krag shooter too] gave me one of his, I shot over the sass marshal target. He thought it was hilarious.

Thanks. But this one can't possibly be solved by handloading (I haven't bought any factory ammo for at least 8 years). The bore axis is actually pointing below the LOS by quite a bit. That was actually how and why I killed my chrony. 0.2" out of short sight radius of 18". It is 38moa ish.

Possibly, you can just dispense with the removable 'top' of the 1903 sight and make a shorter 'dovetail & blade' to install in the fixed 'banded' base.

Obviously, the original Krag rear-sights were not calibrated to work with the 1903 Springfield front-sight.
(I have a couple of Krags that were 'cut-down' and have a 1903 front-sight; I have to set my rear sight for 400 yards to fire to point of aim at 50 yards).

If it matters, I like this idea a lot :crossfingers: And, it would also be easy to purchase a spare/surplus sight and modify that top dovetail part, there is 2/10 to mess with on that.

Also for shimming I strongly advise brass shim stock, not JB crap. Oh god, how I hate that slop on a gun. You may also find longer screws at Brownell. I dont know what they look like. But 0.05 is easy peasy to shim up with real shim stock.

That crude paint edit looks like about 0.15 with a little filing and drilling. Something like that. Or peruse the catalogs for a beaded front dropin.

It is a 1898 rear sight. The front sight is a band type without the dovetail. I did a rough estimate based on bore sighting. I will have to cut down the front sight blade to almost nothing to get it close. That's why I considered shimming the rear sight. JB weld is cool. I have used it quite a bit for similar jobs. No problem.

Thanks gentlemen.

Pictures of what you have would help others help you. (Actually, re-reading your description, in the initial post, suggests that you may have a model 1896 rear-sight).

Don't confuse U.S. sight models with rifle/carbine models. (You can have a model 1896 sight on a "model 1898" marked action).

A 1902 rifle rear-sight base is 'taller' and would likely solve some of your elevation problem.

The different models of Krag rear-sights require specific wooden hand-guards. (I don't know if your 'cut-down' Krag still has a Hand-guard)?

It sounds like your front sight is a '03A3 or some mystery 'banded' sight.

An old "No-Drill" Redfield or Pacific receiver-sight allows for a higher rear-sight mounting.

BTW - U.S. Krag barrel screw-holes for the rear-sight, all have the same spacing, and take a .156"X 30 T.P.I. screw. You won't find those at ACE Hardware or most gun shops.

Well if you know a good gunsmith you can get a reproduction front sight and have it silver soldered in place correctly. Depends on how you want to treat your gun I guess. It's not hard to do. I have an 1899 carbine I put a rifle barrel in and turned down then had the front sight re-installed.

Those blade front sights did come in different heights. Maybe check with some of the parts houses and see what they offer. From your oic they are only held in place with a small cross pin. Or check out your local locksmith and look for one of the old nickle silver keys and make your own front sight blade. My 1895 came with a old silver dime as the front sight blade. Frank
