There was a good add on a Trijicon facebook page promoting the Trijicon SRS sight and it was mostly about rail space.  That is an issue that I personally have run into because I put several things on my LWRC M6A1 rifle that I started to run out of room when i tried to put a pressure switch on it.  I started out with a vertical foregrip and it worked well with the my Streamlight Scorpion flashlight but after I fell in love with the Magpul angled foregrip I ran into issues trying to activate the flashlight.   I’m still not sure what I’m going to do but once I get the new XPS sights in from Eotech i’m going to retire my Eotech 512 just based on rail space.

Run time is important but there are differences between military applications and Law Enforcement applications.  There have been big changes in the industry and now that solar/battery optics are are on the market we’ll see what the next generation of Eotech sights are going to produce.   The Eotech magnifier is a very good idea for someone that already has an Eotech device and wants to make it a medium range optic.  The side battery switch is something I also really like because it makes it easier to get to if you already have a magnifier and rear sight.
