Changing the front sight of a match rifle?

Question

I just bought a match rifle today (Weihrauch HW 660 to be exact), and it came with several front apertures and I was wondering how to change them.

Bound's hubby here:

CAUTION: Depending on the type of insert that you have, they can be VERY fragile. You could, depending on the type of insert, crush it between your thumb and forefinger.

Your match rifle has a globe front sight. On the globe is a knurled ring. Using finger pressure rotate (unscrew) this ring, this holds the insert in place. You may not need to completely remove this knurled ring (screw) if you see a cut across the top of the globe. If there is a cut across the top of the globe back up the screw to open up the cut. If there is not a cut, you need to completely remove the screw.

There will be two projections coming out of the globe, probably one at three o'clock and one at nine o'clock. Tenderly, between your index finger and thumb, grasp the projections and slide them toward the removed screw. (Pay attention to how your sight is coming apart, you will have to reassemble your sight in the reverse of what you're doing.) Take the new insert and set it in the globe, just opposite of the way you took it out. NOTE: the projections will probably be of different sizes so you may have to flip the insert for it to fit into the globe properly. Once the insert smoothly slides into the globe, carefully reinsert the screw and finger tighten the screw against the insert. DO NOT overtighten the screw! When the screw is inserted properly, the insert will be snug and secure in the globe. It will not move.

A few points to keep in mind:
1. the inserts are small and delicate, do not lose them
2. when you change out your inserts, you should not have to re-zero your target rifle
3. if you are using an aperture (ring) insert you may need to change the insert for each distance that you shoot (50 feet, 50 yards, 50 meters and 100 yards)
4. if using an aperture insert, when you center the bullseye in the front aperture you want a small ring of white between the blurred black of the target and the defined ring of the aperture
5. treat these apertures as if they were gold, to replace them could be expensive.

It looks like you have a very fine .22 caliber target rifle. When I was shooting .22s I do not remember this brand or this model. The most common match .22s were the Remington 40XR, the Winchester 52D, the Anschutz 1413 and the Walthers rifles. For local matches, where the competition wasn't all that keen, I used CCI "Green Tag". For serious matches (state regional and national matches), I went the extra 10 yards and bought Eley "10 X". You need to find which .22 shell shoots better in your rifle. If you are shooting NRA, not ISU matches, remember to use your padded glove. Make sure that you try outdoor three position and outdoor prone matches. You will learn alot and have a ball.

Good luck!

The manual should say. If not, go onto their website if they have one and either download it or contact them to request one.
