Trijicon have updated their mini red dot RMR sight. They claim the new model is tougher than any other mini red dot available.

When precision is the only option, your best option is the Trijicon RMR™ Sight. Built to provide optimum red-dot visibility against the target, you can acquire and hit your target quickly and more accurately.
The new Trijicon RMR™ (Ruggedized Miniature Reflex) has been introduced to match the legendary toughness of the Trijicon ACOG® (Advanced Combat Optical Gunsight).
It can be teamed up with the ACOG® or AccuPoint® for the ultimate in fast target acquisition or precise aiming at extended distances.
They start at $425.
DefenseReview has info on new FERFRANS FAS combat optic/sight
“This concept started when my instructor for the FERFRANS Full-Auto Course complained that the aimpoint and the EOTech [550-series] was too big for a sighting system. He opted to use the iron sights. So we did a lot of testing and he finally agreed that the red dot or the EOTech’s circle dot is faster, but it’s too big that it will block his view. So I thought of a smaller sight that is compact and small like the DocterSight. The only problem [with] the DocterSight is it is not robust enough for combat duty. So we created the FAS. I had some Navy SEALs test it in our full-auto course and they all love it. There were civilians that tested the fast and they have nothing negative to say about it. The dot is 3MOA. It uses a lithium battery 3V, CR2032. It similar to the DocterSight. It has a brightness sensor with the Seals using it at noon time with no problems of brightness. All other specifications are the same as the DocterSight.”
The FERFRANS FAS combat optic/sight is ideally-suited to CQB/CQC applications, but it can also be used to engage targets out to medium distances (as far as 200-300 yards) with its 3-MOA dot.
