Those are contradictory requirements.
Yeah... I'm probably asking too much to get both from one rifle.
My original plan was to get a Bushmaster BAR-10 rifle, and set it up for long range work with a mildot Leopuld 4-14X; and a Bushmaster BAR-10 carbine with an Aimpoint for CQB work. But they keep dragging their feet about making spare parts available, and I don't want to sink $3000 into a system with no spare parts readily available.
So I'm thinking I'll get an FAL in the meantime.
