Very interested in getting a rear BUIS, but am new to them. I have a YHM flip-up front gas block sight on the way. Want to make sure the rear BUIS I get is compatible.
I'll be using it on a flat top upper, with an Aimpoint in a cantilever mount.
Which rear BUIS should I get?
BTW - I may also use a scope as well (swap-out) and will eventually replace the Aimpoint with a Trijicon Tri-power.
Thanks for the advice.
