Well I can only say how good this sight is on a recent drive I shot a pig and a fox both running at full tilt.
It travelled to germany and back on the ferry and on tractor and trailers on the days and I checked it yesteday for this weekends trip and it is still zeroed.
Using it free hand on my 7mm rem mag at 55m's I can get a 3 inch group.
Its all metal and very well put together.
I took a Zeiss 3-12x56 off the rifle and fitted this.
I am not sorry.
