Swiss K-11 Sights

[milrifle]

When shooting cast in my 03-A3, I adjust my sights to about 350 yards to hit the target at 100 yards. This using the Lee C312-185-1R with 26 gr of RL-7 at 1700-1800 fps. Using that same bullet and load in my 7.5 x 55 K-11 with the sights at their lowest setting (300 meters), it shoots 10" high. I was kinda expecting it to be dead on, based on my 03-A3 experience. I didn't chrono the loads but wish I had.

At 10" high, my calculations show I would need to either file .053" off the rear sight or else add that amount to the front sight. I'm not fond of either of those solutions. Reducing the load to 22 gr. of RL-7 brought the group down, but opened it up. I could pursue this, as I didn't shoot enough to make a scientific decision, but like I say, initial results showed this load to be inferior to the 26 gr.

So what are you other K-11 shooters doing? Loading light? Modifying sights? Also, did the smaller case volume of the 7.5 x 55 increase my velocity that much over my 30-06 with the same load? One would think similar sight adjustments and similar muzzle velocity would yield similar POI, unless of course my muzzle velocity was NOT similar. Again, I wish I had chrono'd the loads.

How about a clamp on front sight?

the k-11 [98/11] sights are based on a lower pressure round.
the 98 was a x53 the 11 was a x54 and then the 31 was the x55.
they were recut to the longer round when the 98/11 was introduced/arsenaled so there was a step forward.
each step also precluded the older rifles using the higher pressure rounds.

when the 31 was made they needed a more modern round.
and the x55 gp-11 round was introduced so that everything was cut the same and used the same ammo.
all the spec's were tightened up,and anything out of those spec's were discarded as scrap.

The K-11 is cut for the "modern" GP 11 round (7.5x55)

The clamp on sight would probably work. I may look into that. I'm also thinking about maybe building up with JB Weld and file to shape, or else Super Glue a piece of metal to the front sight. Soldering or brazing seem a little too 'permanent' in my mind.

Milrifle,

A taller replacement front sight can be installed very quickly and easily. File it down to get your POI for whatever load and range you want. This is very commonly done.

The original sight can be re-installed if desired.

Had the same problem with my G96/11 so I picked up an extra front sight blade and soldered a piece of 1/16" brass rod to the top, then, filed it to proper height for 100M zero. Picked up the replacement sight from GunParts USA (Numrich) but it looks like they're out of stock now. You might try either www.surplusrifle.com/ or www.swissrifles.com/ for other parts sources.

Thanks guys.

I did a search for the taller front sight. Seems a company in Tennessee used to carry them, but is now out of business. I found a guy on another forum that sells them. It would appear he lives in Europe. I sent him an e-mail. Hopefully, I can get one from him.

The Swiss military actually had five different height sights and four or five widths from what I have read. Unfortunately, the tallest of them looks like it would still be too short to get me zeroed at 100 yards. This guy looks to have all these in stock, new and used, except for the used tall ones. Of course, the price for the extra tall aftermarket one is more than the military surplus ones, but you gotta do what you gotta do.

[milrifle]

Well, no luck with that guy. Anyone know where to find these extra tall front sights that replace the existing standard height ones?

Milrifle;

I have a K31 that I use for long range shooting. When I first got the rifle I was puzzled by the coarse adjustment notches on the issue sight.

My idea was to modify the sight so I ordered another from the parts supplier, then modified it as follows: I got an old hammered-out Lyman 66 receiver sight, cut off the staff at the windage cross piece and welded it to the cut-down issue sight off the K31.

Like this;

The way I decided to adjust for elevation was the 6-40 cap screw you see in the photographs. I drilled and tapped holes on both sides of the aperture because I often shoot in conditions where one side or the other will be obscured by the adjustment screw unless there is an alternative.

For tracking elevation I simply use a machinist's scale calibrated in 100ths of an inch. I measure from the bottom of the machine screw cap to the top of the sight. This sounds clumsy but really, its no problem at all and repeats dead-nuts.

This simple fix works for precision adjustment for both elevation and windage.

I retained the original sight and swap back to it when I enter the rifle in "As-Issued" matches.

Good afternoon,

The ones i showed i do myself.
If you state how high your favorite load shoots at a given distance and the length between sights, i can do you one in a couple of days. Oh and diameter of barrel in front of the front sight also.

[milrifle]

I appreciate the offer, but I think I'm gonna solder a piece to the front sight. That would be reversible if I ever needed to reverse it, but won't be too noticeable, if I take my time with it.

[milrifle]

OK guys, I did it. I removed the sight, lightly filed the parkerizing off, tinned it, tinned a piece of brass, and finally stuck them together and hit them with the torch one final time. Did some final filing and blackened it with a sharpie marker and reinstalled it. Looks pretty good. It will be plenty tall enough to get me on target. I'll probably do some more filing to get it to zero at 100 yds on the 300 or maybe 400 meter setting. Going with the 400 meter setting will allow lowering of the sight if needed in the future.

Milrifle,
newbie
could you have not just replaced the rear sight with a 100m one? your front sight does look nice though

[milrifle]

I'm not sure the rifle sight will fit the carbine, but even so, I didn't have one to try. I was able to do this for free with items I had on hand. Other than the removal of the finish, it is totally reversible if I were to want to go back to the original sight.

[Hang Fire]

How about a clamp on front sight?

That is one fine idea, thanks for posting.

[Chicken Thief]

I did an intire thread on them. There's way more pics.

[waksupi]

I would be interested in the take-off sight, if you want to part with it.

[milrifle]

Wakeup,

Sorry, but I have only the one sight. I just modified the one that was on the rifle then reinstalled it.

[milrifle]

Oops. Sorry about the name spelling. Dang smartphone thinks its smarter than me.

[gwpercle]

Check out the Mojo sight for the K-11. Midway sells them, replaces the original rear and is adjustable. No permenant damage done to rifle, you can put the old sight back on with no problem. I like mine.

I notice that posters are referring to a "K-11". Does this cover the Schmidt-Rubin 1896/11, the Schmidt-Rubin 1911 as well as what one described as 98/11?

I just purchased a M1911 which the seller also described as a K-11 but did not apply that to an 1896/11. I need to get more familiar with these rifles since I also have 2 K-31's.

[Chicken Thief]

The 1911 is a full length rifle of 1.30m~52"
The K11 is a karbine version of the rifle and "only" 1.10m~44"

Loads of good info here:

[alamogunr]

Thanks for that info. I guess the vendor knew what he was doing. He described the carbine as K11. I wanted the "long" rifle. I hope it turns out to be a good cast boolet shooter.

I had the swissrifle site bookmarked but had forgotten about it.
