Just bought a H&K model 91 looking for some help with scope selection. Do you need the tool they sell for rear sight dioptic or will a regular screw driver work?

First congratulations on buying a H&K 91. I have been using one since 1977. It is one of, if not my most favorite rifle. I have actually hunted with it quite a bit, taking several, wild pigs, deer, turkeys and antelope with it.

To adjust the windage on the rear sight a regular phillips screwdriver will work. However to adjust the elevation you will need either the factory sight adjustment tool or a good pair of forceps/tweezers. If youn look into the reat sight you will see two plungers that must be prerssed inwards to ritate the rear sight drum. One revolution of the drum moves the point of impact 5.3" at 100 yards.
Sight the rifle in at 200 yards/meters with the "2" aperature.


As to a scope, IF you can find one of the factory Hendsolt 4X scopes in the factory mount, get it. They are an excellent piece of kit. They have a ballistic cam that goes to 600 meters.

If you want a more powerful scope get one of the factory mounts with the 30mm rings. The factory mounts go on and off the rifle with no loss of zero. My scope has stayed zeroed since 1977...

The 22LR conversion kit is also well worth the money. It is as accurate as most expensive 22LR's, and it works 100%.

You just set the iron sights to 400 Meters, or the scope to 400 meters and you are zeroed at 25 yards.

Both the aluminium and the steel magazines work great. Check with Cheaper than dirt.

The barrel is totally free floating, so the factory bipod will not change the point of impact.

Likewise you can shoot 60 rounds or more, as fast as you can, and the zero/point of aim/point of impact will not change.

I also really like, and use a lot, the factory retractable buttstock.

It makes the H&K 91 into a very compact transportable package.

I have never had any malfunctions with the 91 shooting standard factory lead pointed hunting ammo, from 150 to 180 grains.

Don't mean to hijack the thread but what do you think about the PTR 91, the poor man's HK-91?

PTR actually bought some of the original G3 making machinery from one of the H&K licenesed makers in a Foreign country.

They had some problems early on, and some problems when they changed the number of flutes in the barrel from 12 to a lesser number. They had some functioning problems with some ammo. They upped the number of flutes, but still had less than 12, except for their Military copy of the G3/91, where they used the standard profile 18" barrel with 12 flutes.
They also has some barrel trunions crack, but...
From what I have read they have stood behind their rifles and corrected any of the problems they have had.

I do praise them for making the investment, and going to the trouble to make a 91 here in America.

The 91, once you understand why it was designed the way it was designed, and once you shoot one a bit, and understand it, you may come to the conclusion that it is one great rifle.

I like a LOT of different rifles, but the H&K 91 is one of my most favorites.
I have been shooting one since 1977.

PSmith I say give the PTR a try, and keep us posted.
