Sightron dilemma

[Hillhunter]

Had this post earlier today but I deleted by mistake . I bought a new Sightron 10 x 50 last month to find after many rounds and hours later that the ocular lens was moving , to the extent that at 300 yards I could move the dote at least 10 inches in all directions . I could land one bullet on top of another for 2-3 shots then it would move approx 2 inches right and down the same . Again I could land 2 shots in the same place and it would move again. I contacted the dealer where I bought it and he said he had never heard of this before and he replaced it .I received the new scope yesterday , mounted it on the rifle , set the ocular to my eye , approx 6 mm out from the bell and again I could move the dot all over the place , it's like the threads are too loose . As I have a competition shortly my only remedy was to put a cable wrap between the ocular lens and the bell and lock the ocular as tight as I could . Has anyone had this problem ? Seems to me that the lens needs a locking ring as in other sightrons. I must say that my dealer had no problem replacing the last one but he is amazed that the second one has the same problem.

Probability goes down the more scopes 'fail', and likelihood of other causes goes up. If you sandbag the unit with deadcenter hold and wiggle the ocular very gently, does the poa move? Did the quick fix solve the problem completely, in which case mebbe a bad run of scopes. Were the serial numbers close together? Or is it a 'slow mirage' problem just showing up on 50 X. As always, more data. Seymour

Spot on Seymour , when sand bagged hold and wiggle the poi moves at least 10 inches in all directions , yes the quick fix solves the problem , maybe you are right , a bad batch , I didn't check the serial numbers , thanks

My 10-50X60 will do the same thing with the eye piece unscrewed all the way , I have done something similar to what you have done and I do it to ALL scopes I have that do not utilize a lockring.

I've wasted more time than I care to delve into shipping things back that have flaws and in this case it is not a manufacturer defect but rather a design flaw..

After my second go round (with a different manufacturer) I did something along the lines if what you've done... I take a stack of thick O-rings (for my particular needs only 2 were required) and place them in a bowl of water and stick em in the microwave till the water boils , then take and while they are soft from the heat slide them over the ocular lens so that you now have something to tighten against.

Being O-rings they will expand should you need to unscrew the ocular lens for fine tunement.

Good idea , I will try that

Is it only the 10-50's that have this problem or do the 8-32's also have this problem?

Just my personal experience , but it's not uncommon with any occular piece that is unscrewed to it's fullest and does not have a lock ring.. Once it's either snugged up to something or brought in to approx. 50% of it's extension the problem appears to resolve itself...

I had this arguement with a friend about his scope, he claimed there is no way there was any play in his "High dollar" scope... We unscrewed the eye piece out aprox. 3/4 the way... There was minute amounts of slop there.. Why he did'nt notice it was perhaps the same reason I didn't at first , because I wasnt unscrewing the occular that far for my particular shooting.

I have 2 Sightron lll 10-50x60 scopes and have had no problem at all with the eyepiece moving while shooting. I shoot with the eyepiece almost all the way out when I shoot without my eye glasses and this is how I shoot most of the time. With my eye glasses on it is at about mid-range and if I use my BulzEye scope eyepiece attached I have the eyepiece screwed just about all the way in. I have had no problems with unwanted eyepiece movement at any lens position.

snakepit, how do you like the BulzEye scope eyepiece?
Thinking on buying on some day.
thanks van

I have to set the eyepiece ( ocular ring ) approx a quarter out and that is where the problem is , there is too much slack in the threads , if I could shoot with it all the way out there would not be a problem as it would have something to bottom out against , I have to wait until tomorrow to speak to the supplier , but I feel as some people have said these two I have received must be a bad batch , will keep you all posted.

In my post I said I shoot with the eyepiece almost all the way out and just about all the way in. In a discussion with a Sightron Tech Rep when I purchased the first of my two 10-50x60 and how I usually do not use my glasses but turn the eyepiece just about all the way out he said that was OK but not to go completely out or completely in because of some ocular reason that I do not recall what it was about. So as I said I never adjust it all the way or as you say bottom it out and if I wear my glasses it is set at about the mid point.

I also contacted a couple of my friends who also use the Sightron 10-50x60 and they have not encountered the problem you are having.

Have you contacted Sightron about this and if so what was their response.

Van, I will send you a PM about it.

I am waiting to talk to the supplier later today to see what he says

Is it only the 10-50's that have this problem or do the 8-32's also have this problem?

I would think all scopes that don't have a locking ring would have the same effect when threaded that far out.. I would bet somewhere in the directions it states only so far.

[lal357]

i've never had that or any problem with mine

 

[Raythemanroe]

I have read this before and the first thing I did was try to move the ocular. My 10-50 seems to be as solid as my Leupold so I gotta believe that the scope is being over adjusted...

I think it must be a bad batch , supplier is contacting sightron today, as far as screwing out the ocular too far is concerned , i only have it screwed out quarter way, it is like there is too much play in the threads . I know sightron are good as i have two more but they have a locking ring.
