Mounted correctly the e-bay mounts work fine. Mine has held zero (with very minor adjustments) for a couple of years and ~1200 rounds.
Installation pointers (I have installed 3 so far):
1. Do not use the rear sight pivot screws (supplied with the mount). Instead drill-out the mount pivot hole, so the old mounting pin fits relatively snug, and use the original rear sight mounting pin.
2. Make sure that the set screws (small screws on the side of the mount that lock the primary elevation screws) are backed out a full turn. Many people do not and end up with a stripped elevation screw.
3. There are 3 elevation screws. The front screw (in front of the sight mounting pin) is used for all MN models as the forward pressure/adjust point. The center elevation screw is used for M38 & M44, the rear elevation screw is used for M91 and M91/30. Remove the screw not being used and save as an extra. Do NOT use all 3 elevation screws.
4. Never overtighten the elevation screws. Snug is good enough.
5. Course adjust the mount using a torpedo level. First level the rifle at the receiver, then level the mount using elevation screws.
6. Once the elevation is course adjusted, tighten the set screws. Again, snug is good (do not overtighten).
That's it. During the first firing (I recommend 40 rounds minimum) check the mount about every 5-10 rounds to insure it is staying put. If it comes loose then you probably didn't tighten the set screws.
And finally....MAKE SURE that you have checked and tightened the two action mounting screws each time before shooting.
Any questions... let me know.
