Or, what exactly is that? I sent my Type 1 RMR to Trijicon because it wouldn't stay on. I honestly expected a Type 2 replacement. Not that I wanted one but I'd heard that was common for returned Type 1's. I got my same unit back, with the work performed noted as: "Added gussets".
It looks the exact same. And seems to be working just fine now, no complaints about that. Just wondering what they actually did.
