Daystate Why is the Daystate Blackwolf scope mount different front and back?

[drdirk]

I have had my Blackwolf now for a few weeks and still struggle to put a scope on it. Strangly none of the scope mounts I bought or had fit the rear rail. The front seems like a normal Picatinny but the rear is always loose, no matter what rings. I even took off my Barrett expensive rings and it will just not fit. Take a look at the photo. The front rail looks normal but the rear rail just will not fit any of the 3 scope mounts I tried. So maybe I am an idiot or I am venting, but that is just stupid. Am I missing something? Will the rear only accept a special kind of ring and if so why would they do that??? Any help is appreciated!

I thought I finally buy myself a high end airgun and it looks amazing and sold but that seems like a really stupid thing to do and for no reason. Venting!!!!

Update to my post above, I measured with width of the front and rear rail section and they do NOT appear to be the same. The measurements are attached. I am not the best mechanic but this difference appears pretty substantial. The front section is about 20.80 mm and the rear is quite a bit narrower at 20.14 mm than the front using my same micrometer and imperfect technique. The spec is 21.1 mm from my searches . So both are a bit narrower with the rear too narrow to effectively clamp a ring.

This with the fact that 4 rings of different manufacturers are loose on the rear seems to all point to a factory defect in tolerances.

I then called AOA and explained the above. They were great and are in the process of issuing an RMA to check it out. We discussed that I would sent my rings with it. While this is frustrating the fact that AOA immediately answered my call and offered to look at the rifle is nice in today's world!

If you have a Daystate Blackwolf you may want to make sure your front AND rear rings can be tightened. The first time I mounted a scope I actually missed this and in hindsight found out that my scope was only held in place by the front ring.

I was going to measure the width of the front and back picatinny rail on mine but the digital caliper ran out of battery so no way of check for the time being. But I'm using Vortex Pro riflescope rings, no issue I can see. My scope seems pretty solid with those scope rings.

I’ll pull the scope off my buddy’s BW this weekend and measure. AOA is great and Daystate has a 5 year warranty so whatever the issue is they will resolve it.
update:
i pulled the scope and measured both front a back sections of the picatinny rails.
I measured in several sections along both front and back Rails.
I’m not a machinist so bear with me. Both
The front section and the rear sections widths varied from 20.86 mm wide to 21.07 in width. My observation is that they are the same, as both sections are varied the same depending on where you place the micrometer.
i had no problem with my Nightforce rings being able to properly secure the scope.
the gun was still at zero when the scope was reinstalled and tightened.

Maybe it was a manufacturing defect out of spec. Should be an easy fix if they have a replacement.

I read this somewhere else as well. Same thing, scope rails narrower than standard pic. I’m sure they will set it right as it’s an unacceptable thing, esp at this price.

Yes I reported it from the start and they though i was smoking somthing. But info above is correct.
