This thing got announced over a year ago, and seems to be at some euro dealers (this is from a German dealer, who clearly took their own photos so they have at least ONE and say it is in stock, in clearly production packaging as that is really similar to their other boxes but has foil printing so cannot be done one-off), but is not yet in the US. I have asked Mepro, have nothing but that it is definitely not cancelled, is coming "this year"
Anyway, it's a replacement set of tritium sights, with the rear having a mounting rail and set screw. Aimpoint makes something like this for mounting the T2 IIRC:
The sight is normal MRDS layout, but buttons on the side. Big ones...
And attaches with a big lever on the right. Screw on the left presumably works like all their rifle sized RDS, allows changing tension to fit the mount rail
I am sure you can get used to the sight picture, but it's not the slickest thing ever. Protruding controls, and that rail lever is odd since their full size RDS has quite amazingly non-protruding levers.
I want to see the "version 2" with slicker controls, and a smaller rail lever. Bet they could drop the sight window down also, get cleverer about the overall packaging.
But I am interesting in how you can dump the sight if needed. Both easier to replace at the armory, and is interesting to see that it goes with the mindset of rifle RDS: it is reliable, so use it and have the marginal ability to ditch and go to irons if you really, really have an issue.
I am not sure Mepro makes projects like this for the hell of it. Not sure they have done anything electronic without an IDF requirement. So, wonder what that req sheet looks like and why, even if not adopted.
