Trouble with Tec-hro precise sight.

[turtlehead]

Recently purchased this sight. Problem is that my adjustable gehmann iris with magnifier or without magnifier and a 577 adapter doesn't quite thread in right. The threads in sight seem to be .5mm or so larger. Has anyone had any experience like this?

[TenMetrePeter]

The ad says Anschutz and Gehmann compatible so all threads should be 9.5mm x1mm pitch so I can't think what the problem is unless your 577 adapter is a Gamo size 9.0mm x 1mm pitch.

But even the threads on the magnifier are the same as adapter???

Yes doesn't make sense. Can you measure the male thread diameter accurately?

[turtlehead]

I will this weekend. Friend a machinist with proper tools to measure accurately

Is that all the detail you want to share with people who tried to help you?

[turtlehead]

As of right now, yes. Not to be a jerk, but need to see the outcome of Tec-hro standing by their product or not. Will update you as soon as I can.

The threads in diopter are 10mm x 1. All irises are 9.5mm x 1. They admitted their "producer" must have made a mistake. They checked their stock and all were the same 10mm x1. Now they say that, " In their eyes, they see no problem."

They were gonna send me a new sight diopter.

[TenMetrePeter]

oops! Accidentally cut a batch of sights at 10mm LOL!

[turtlehead]

Yeah, and maybe won't stand good for them

Somebody got fired....

Ok. Update. All is well. Tec-hro is standing by the mistake and sending me a new diopter.
