I reconfigured my AR-15 for CQC (Close Quarters Combat). I stripped everything off it that adds any weight, including iron sights, and moved to a Sig Sauer MSR red dot reflex.
@trinsec For now, yes, i might buy a 3x flip away magnifier and i may add light weight irons at a 45 degree... but im trying to keep it as light as possible... I also might switch out the picatinny rails in the front for a lighter polymer grip.
