Question for Sightron owners......

#1 Postby ihmsakiwi » Mon Sep 30, 2019 4:59 pm

I bought a new Sightron 10-50 x 60 about 6 months ago. Not the newer zero-stop model.

Booklet says it has resettable turrets. I read they need a 1.5mm Allen-key to loosen.
I can't get the allen-key to actually connect internally with a "slot". Is 1.5mm the correct allen-key in fact? I have tried all my sizes to no avail. Peter

Hi

I have 2 Sightron 8-32 X 56 S111 scopes. The Allen key I use to change the turret position is either a 1.27mm or a .05 inch. The screw is a long way down in the hole.

Hope this helps.

Allan

Thanks Allan. I'll go to my tool shop tomorrow. Is there such a thing as a 1.27mm off the shelf allen key?

The ones I have are part of two sets (one metric one imperial) of small allen keys made by Kinchrome.

It will probably be 0.0625” or 1/16 imperial, quite often in better sets, I can recommend bondhus ball end as excellent, Bunnings generally has them, cheers Rich

Hi, got a response from Sightron over-night. 1.27mm Hex required which equates to 50 thou.
Bought oner today so will zero scope tonight.
Thanks for the replies.

My Sightrons all came with a Allen Key of the correct size.

Cheers

The correct Allen key is the smallest one in the Imperial set marked "50". Sightrons are made to U.S. Specs so its all Imperial. A normal set of Allen keys doesn't usually go down to that size so you need to look around for a more complete set. Bunnings (of course) has them.
Its best to use the "ball" end and as someone said they are very deep holes so poke done a long way until you feel it engage.
Cheers
