Just ordered my first BCM URG. It'll be a 14.5 mid-length with FSB and DD 9" lite handguards. I'll be running her on my spikes assembled with DD lpk and vltor A5 Emod until my BCM blem lower arrives. I'll put an Aimpoint T1 on a larue 660 and we'll be ready to roll. As this will be my first red dot ( I've always had holographic ) does anyone suggest 4moa or 2moa dots? I would like to be able to reach out to 250m max.
