Don't recall saying I do know of any. Every scope manufacturer that I own with the exception of Burris has a Canadian repair or replacement facility.I know that it is a huge pita to have a Burris warrantied and I am not looking forward to it if the need arises. Regardless,the 10 yr international warranty on Sightron is enough to steer me away. I'm not implying that Sightron is bad optics at all,In fact ,I'm sure that they are nice quality optics.However,some here are implying that they are fail proof. Bs, there is no such optic.Some here have even made the inference that if an optic comes with an exceptional warranty,it is likely junk.Again,that's Bs.
It is not 10 years it a lifetime warranty . It is right on their site.
