Aimpoint is debuting their pistol/SMG sizes MRDS in 6/11. It’s large, but it’s the only closed unit on the market. And it’s Aimpoint. Those Swedes are like Germans, with higher standards.
Curious as to what the mounting pattern is. If I had to guess, a mini-1913 kind of clamping system, based on the very few pictures I've seen on the Internet? Either way, these will be replacing my RMRs, as I have the Type 1s. I've not had any issues that couldn't be solved with a fresh battery, but no matter how you spin it, an open emitter system will be more susceptible to debris. Also, note that the spec sheet appears to have the length and height swapped, based off of the actual pictures of the sight.
Guess Mark will be getting yet more of my business when these things drop.
