For anyone following. I found a guy who imports from the US to the UK and sells on Amazon of all places. Duty paid was 31 quid.
It only arrived the other day and I’m away for a couple of days. Will try swapping it out when I get back.
Thanks to all who commented with suggestions, I’ll update...
Not the best pictures, daylight would be better.
But looking at the pictures zoomed in it does look dovetailed.
It’s a shame, because I actually like the sight. But parts over here are next to nonexistent.
I’ll get it out and take a couple of pictures.
I doubt I can measure the difference in one side or the other. I don’t have a caliper here.
Is there a normal in and out direction?
I think it’s factory. It’s a 500 ATP.
It’s smooth bore, not a rifled barrel.
I think I can see the dovetail now, is it an interference fit, which way will it come out?
