I have an anti with a March scope. Zero clearance issues. Works great. This Tenacity has a thicker bolt handle.
I called Defiance a couple days ago. They had no easy options for me. The bolt handle on the Tenacity is not interchangeable like on the Rebels or Anti. They said that they have updated the entire bolt design for less throw angle and that per my serial number I had one of the older ones. They did offer to replace the bolt but I needed to send the whole rifle back in to them, or tear it down and send the receiver back for fitting and head spacing.
No thanks. If I can’t find a suitable scope/ring combo I’m going to take a grinder to the handle myself and then just have it Cerakoted.
