Hi

I need to get a 5.5mm sight riser block made for my Anschutz 1813 rear sight.
Does anyone know the angle of the dovetails cut into the barrel?? I thought they were 30degs but that doesn't seem to work out correct. Any other dimensions would also be very helpful, they are not very easy to measure.

Thanks
Henry

Have a word with Barry Nesom he should be able to help you.

Hi Henry, I have copy/ pasted a post from Eric U that explanes your question. But the picture wont copy. Search function is you friend.

Cheers Glen Turner.



All of the FWB, Walther, Anschutz dovetails (except Walther front sight) are considered to be 11mm. They are just a little different though. The FWB dovetail is about .024" (.61mm) wider than Anschutz so some of the older ANS sights that fit quite snugly on the ANS dovetail probably won't work on FWB. FWB sights would probably work fine on ANS, but who in their right mind would do that? The Walther front sight dovetail is quite a bit smaller than their rear dovetail for some strange reason. All of the mentioned manufacturers use 60* dovetails.

Older Anschutz front sights that fit on a sight block are not interchangeable with the newer ones that fit on a dovetail.

The only way to accurately measure dovetails is with precision pins of a known diameter and micrometer or calipers. Measuring the width of the top of a dovetail is pointless as different manufacturers have different height dovetails. They are still considered 11mm. Measuring the dovetail bottom width directly with calipers is also pointless because neither the caliper jaws nor the dovetail cutter itself are dead sharp...so what exactly are you measuring?

I'm not exactly sure what dimension these European manufacturers are referencing by their 11mm dimension designation. I just use the attached measuring method to make sure anything I make has dovetails that are the same as the manufacturer.

I'm not 100% certain, but I think ESP is out of business.

Just food for thought,
Eric U
