The Pennsylvania Firearms Development Corporation hereby disclaims all warranties not expressly written here, whether express or implied, including any warranty of merchantability and any warranty of fitness for a particular use.

The Pennsylvania Firearms Development Corporation will not be liable for any other damages, including any incidental or consequential damages, resulting from the use of one of its sight rails.


The newest U.S. Krag rifles in existence are now over 110 years old. They have been used and stored in many different ways, under a variety of conditions. Many of them have been previously modified by unknown persons. It is possible your rifle has been subjected to conditions or previous modifications which render it unsafe to fire. Firing a rifle with certain defects (e.g., metallurgical defects; improper head spacing; obstructed bore) can cause the barrel, chamber or receiver to explode upon firing, causing serious personal injury or even death to the operator of the rifle and/or others in proximity to the operator of the rifle. The Pennsylvania Firearms Development Corporation cannot possibly know the condition of any purchaser’s particular rifle. It is, therefore, the sole responsibility of the purchaser of Kraghaus brand sight rails to be certain the particular rifle upon which the Kraghaus sight rail is installed is in serviceable condition and can safely be fired. The purchaser of any Kraghaus sight rail assume all risks of loss, damage or injury by reason of the use of any Kraghaus rail on a rifle which is unsafe to fire by reason of age, prior modification, prior conditions under which the rifle was stored or used, or unsafe installation of the Kraghaus sight rail. If you have any doubts or questions about the condition of your rifle, the Pennsylvania Firearms Development Corporation strongly recommends that you consult with a competent, professional gunsmith, and have him or her examine your specific rifle.


There original “factory” screws used on the various sights mounted on U.S. Krag rifles from the Model 1892 through the Model 1901 are now obsolete. They were 4 mm. (diameter .159”) with a 0.10” pitch, and very hard to find.

Over the years, people have used screws salvaged from one sight to attach another, or have forced the threads using screws that “looked close.” Forcing the threads often worked the first time, but damaged the threads. The next time the screw was removed and put back, they would not hold. This would later confuse people who removed the sight and assumed the screws they just removed were the right size, but the threads would not hold. Sometimes the holes were re-tapped to accommodate another type of screw. We therefore find a lot of different screws used on “sporterized” Krag rifles, which is why no screws are provided with these rails.

If you still have your original Krag rear sight screws, and the threads are still sound, you can use the Krag screws to attach these rails, except the screws for the Model 1901 rear sight. If you have a Model 1901 rear sight, you will have to get screws from one of the several earlier models of Krag rear sight. The threads are the same, but the screw heads are different.

The bore and countersink on the Kraghaus rails are sized for the more common Krag screws. If, however, your rifle has been drilled out and re-tapped, the Kraghaus rails, being aluminum, can easily be modified to fit a wide variety of modern screws.

If you have thread damage (red Locktite® in the holes is a sure sign), we recommend having a gunsmith bore out damaged threads and re-tap the holes to accommodate modern screws. We believe using modern screws will save a lot of time and aggravation in the long run. (Of course, this should not be done to an all-original, “collectable” arm, as it will diminish the collector value of the rifle.)

We strongly recommend that any drilling and tapping be performed by a competent gunsmith who has the proper tools and experience. Drilling too deeply can ruin the barrel, and may cause catastrophic failure of the barrel upon firing, resulting in serious personal injury or even death to the rifleman or others in proximity to the rifleman.

In addition to possibly drilling too deeply, drilling a crooked hole or improper tapping procedure can create a mess that is difficult to repair, even if it is not severe enough to affect the safety of the rifle. Therefore, drilling and tapping by one other than a qualified gunsmith will void all warranties. The Pennsylvania Firearms Development Corporation cannot be responsible for personal injury or property damage resulting from the use of a Kraghaus brand rail which has been installed by one other than a professional gunsmith.
