Hello,
A few months ago I bought the Gamo Replay 10x IGT springer airgun.
Very powerful and accurate, but this airgun ate 3 different scopes! :-(
The recoil is brutal.
Looking for a solution, I found the Diana Bullseye ZR mount.
Praised by many and quite expensive, but I bought it to see if it really works.
It looked like it worked, but now and then I got some fliers that I could not explain.
I filmed the mount at 240fps and saw that while it protects the riffle from the initial recoil,
the scope returned back and smashed its initial position. Not a very effective design...
So I started a small Arduino project to build a standalone battery powered
high-G recoil meter to measure the actual forces that were exerted on the scopes.
It was not easy because the available accelerometers have a very slow sampling rate
of 1khz and high-G versions were not easy to find. Anyway, the results showed that
the scope felt way more than 400 G! when attached directly on the rail but when put
on the Diana mount, the recoil was indeed less but still considerable.
Many times it reached 400 G. That was when the scope was loosing zero again.
Apart from that, the mount had play and it was centered only on the front with
a conical pin. The accuracy was not bad, but the Gamo without this mount was
more accurate.
Frustrated and after all the money I've spent, I decided to build my own mount from scratch
correcting all the errors that the Diana mount had. The result was not bad!
Maximum g-force exerted was 125 g.
Why they did not build something like that, its beyond me.
Below is a small demonstration.
I hope you like it.
Thanks.
