As I was driving home from the range today thinking about Optics choices for my SCAR 17, I kept thinking about the BROWE Combat Optic.
If you haven't heard of BROWE it was founded by former Trijicon employees who wanted to start their own company to make improvements on the ACOG. The body of the ACOG is made out of titanium for lighter weight, instead of using tritium and fiberoptics the BROWE uses a cr123 battery. The run time is 2000 hours which is about 3 months, but the scope has unique features that extend battery life. The reticle brightness is controlled by a chip that analyzes the brightness at the TARGET and adjusts to that.
The common problem with ACOGs is if you are shooting from inside a darkened building out into bright sun, the reticle is too dim. Conversely if you are shooting into a dark building from outside in full sun the reticle can be too bright. The field expedient way of fixing this problem is throwing some 100 mph tape over the fiber optic strip, or taping a glow stick on top of your fiber optic strip.
The BROWE Target Light Sensing Technology does away with this, but it also has a manual override so you can set it to a particular brightness if you want to.
Another battery saving feature is the Vibration Motion sensor where the reticle turns off after 2 hours of inactivity,
The particular model I have pictured up here is the 7.62x51 nato with a BDC reticle that ranges out to 900 meters. They have a ton of different models for 5.56, .300 blackout, etc, reticles come in red, amber, blue, and green.
