Artillery sight weirdness

Dwight Gruber · 04-30-2002, 11:09 AM

I have had the opportunity now to shoot two Artilleries. With both guns, the inertia of being fired made the rear sight adjusting blocks creep foreward on the sight ramp, causing the guns to begin to shoot high. Is this common to other shooters' experience, or am I just...lucky?

I had a similar problem. The fix will require the removal of the rear sight. Once removed pull out the detent bar and stretch the spring. It worked for me.

I too had this problem, because someone had dissassembled the sight and put it together improperly.

Dwight,

The sight assumed that the target was running away from you and that you missed the first and second shots. It was compensating for the increased distance!

Seriously, a weak spring or worn notches and/or elevation catch can cause this problem. Most well used Artys seem to have this affliction.

I have had the same problem with my arty. It looked like the notches on both the slider and the sight itself were worn. I even tried straping down the sight to no avail. I finally removed the slider and put a drop of LockTite on the sight retaining pin when I put it back together without the slider. Seems to be holding. I figured I could have glued, epoxied, it down, but that is so permanent. I think the inertia of the slider in recoil was causing it to move forward lifting the sight.

If your problem is not corrected by the other suggestions, Unfortunately , you may find that your rear site has only the bare nub of the original sight adjustment teeth that are engaged by the sliding assembly. These teeth should be the same length as the top of the right side of the rear site assembly... Since these guns are very old, it is likely that the teeth on your rear sight assembly have been broken off by years of recoil force. (See the attached photo to see what the teeth are SUPPOSED to look like)

There is no quick fix for this malady... You can either replace the rear site with a reproduction, or you can have a craftsman of the highest skills weld over the broken teeth and then recut them...

My "Frankenartillery" Luger suffers from the same symptoms...

regards, and condolences

Yeah, those bullseye targets sure are skittish...

Yep, the lowest elevation teeth are toast. Ah, well, an 85-year-old gun, seen some use...i'm neither surprised nor disappointed. I should be missing only two teeth when -I'm- 85...

Thanks for the pic and the help.

I have a couple of Eagle artys; and since they have led sheltered lives their teeth are fine.

Will guns whose teeth are still good not have the sight jumping problem? Will moderate shooting tear up the teeth? Who knows, I bet.

What is wrong with the photo?

No one answered; so I will guess the pushbutton is on the wrong side!

Someone improperly assembled the sight with the release button on the wrong side....

The photo came from an auction several months ago...
