I have a Burris TAC30 1X-4X-24mm with ballistic CQ on my Rock River LAR-15 and I love it! I use it for 3 gun matches, personal protection, and hunting. Its very bright and has a huge eye relief. The reticle is set up to shoot out to 600yards. I also like that the reticle is black unless you turn on the red, so if my battery runs out, I still have the black.
