I have heard that the Scar 17 has a reputation of being hard on optics. Has anyone used an Aimpoint on their Scar?

Yes. like lots of different generations of aimpoints and lots of rounds. Not a chance that the SCAR bothers an aimpoint. My go to optic in general for the SCAR, although I'm testing the NF ATACR 1-8 as an alternative. I don't think the SCAR will bother the NF either, but I am not sure how fast I will be using it in the 1x dot mode...

Some discussion:

I had a Comp M2 on mine for a while. Not all that long but maybe 400 rounds or something. The M2 is fine. It was on a 16 inch FAL for years before that and a few thousand rounds, and went right back on the FAL after the SCAR. It's life before the FAL was all M4s. Dam I'm getting old and so is the sight but it's still working great.

I have a 16” and 13” barreled 17S. Depending on how I’m shooting, I’ve equipped them with an Elcan 1.5-6x, EoTech EXPS2-0, and Aimpoint T2. No issues to report with any of these optics.

I would suggest the strongest stiffest mount available whichever optic you choose. My 17 ate a Swarovski 1-6 in a Larue Mount. I went to a Spuhr 1pc mount for it's greater stiffness.

Aimpoints are excellent tough sights but IMHO Unmagnified Red Dot sights don't release the full potential of the Scar 17's ballistics. A tough low powered variable in a stiff mount is a much more useful choice.......
