The "features" on the insight MRDS make it a hugely attractive optic. The durability is simply not there. I have broken 6 or 7 MRDS when having them mounted on pistols. But it's not slide reciprocation thanks killing them, it's little things..... like stripping out the screws on the battery cover so that the sight cannot stay on because of intermittent battery contact, scratching on the front lens surface so bad that you can't look through the site anymore, smashing of the glass on the MRDS and crushing of the plastic housing from blunt force impact.
I ran an MRDS offset from an ACOG on one of my work rifles for a while, but even with the shroud protecting it, I never trusted that it wasn't going to fuck me like all the other MRDS that I had killed. I replaced it with a micro T as soon as I could.
I would take an 4X32 ACOG and an offset micro T over any 1-4x Variable on the market.
