I'm considering this optic for a 10.5 inch barrel 5.56 AR pistol build. I am looking for advice from anyone who has used these optics. I am particularly wondering if the red dot is bright enough to be seen easily. I am used to using Aimpoint Comp M4 and Aimpoint PRO and am pleased with the brightness/definition of the red dot, but have been disappointed by Burris and Vortex red dot sights (red dot not as easy to see, particularly outside during the daytime).
Thanks!
