I just sent this to Techsights but thought I'd post it here to see if anyone has had the same experience:
While adjusting my rear sight I noticed that the aperture (part #13, TS00134) will rotate to the left or right if I twist it with slight finger pressure. Granted that I should not be twisting and rotating it this way in the first place! However - I assume it must be slightly loose so that it can be adjusted with the elevation dial and connecting spring (otherwise how could it move up or down?). Have I managed to place it into a position where it is too loose and needs to be reset somehow? The aperture does not rotate unless I twist it and does not appear to be to be affected by recoil - but I just wanted to write to you to make sure.
Anyone else have this experience and wonder if the rear aperture will move around or not?
Best,
Steve
Steve,
I have noticed this and was slightly concerned. The Marines taught to sweep the sight before getting in the position to fire, so I just have to make sure that the sight is flush before sending rounds down range. 8)
Thanks for the reply. I'm going to assume until I hear otherwise that the aperture has to be loose or else you couldn't adjust it. It seems to slot itself securely in relation to the rest of the sighting apparatus and since recoil from my .22 Ruger is only slight and goes front to back it's probably not an issue. If it is I'm sure the Techsight people or someone here will let me know.

QuoteHI Steve,
If you look at the parts sheet you will notice a spring and ball that contacts the elevation adjustment dial which in turn pushes back on the aperture seating the flat cuts on the treaded stem into a v shaped pocket in the aperture assembly frame. These flats cuts and v pocket ensure that the aperture centers when it is turned to the center position. It also insures that if the aperture is bumped it will go back to the centered position maintaining a zero position. I hope this helps.

Just a follow cup: Spent most of the afternoon on the range with my Ruger 10 22 at 50 yards. I've been working on my cheek weld, trigger pull - the basics. No problem at all with the Techsights - in fact I've started to get really comfortable with them.
Best,
Steve
