I haven't shot my HK94 in about 25 years. I took it to the range today to shoot it and brought my factory HK sight tool along to adjust the sights if need be. The gun was shooting a little low but it appears the factory HK sight tool is not unlocking the sight drum so I can rotate the drum and raise it up. I have used the sight tool in the past on my HK91 and HK93 and it works fine, so I know there is nothing wrong with the sight tool. Is there a special trick to using the HK sight tool with the HK94 factory drum sight or does the HK94 need a different sight tool from the HK91/93?

Note: Possibly the lubricant in the sight drum has hardened over the years and frozen the mechanism???

Some of the sights are just fussy at times. I like the 5" hemostats better as can see what is moving or not.

Very possible... take it apart and clean'er up

good tip.

the two plungers are moving freely and it appears the drum is frozen on the post.

All rear diopter sights use the same tool.
