Thread: Sytong HT70 - Return to zero issues

Morning everyone,
Just after a bit of advice from any Sytong users out there.
I swap my HT70 back and forth a lot between my 22 and 308, and cant seem to get it to return to anywhere close to zero when remounting (up to a foot out on windage at 200m on the 308. Elevation is usually pretty good, within an inch).
I have the Pic rail marked so it goes back in the same spot each time, and always torqued down to the same setting.
At first i thought i must have been forgetting to change the zero setting back to the correct gun, but after double checking, still having the same issue.
When I refit my Element Helix back on the gun, it always returns to within an inch, so i dont think theres an issue with the Pic rail.
Anyone got any tips?
Cheers
