In what order do you put the following attributes for your fighting rifle (most important first)?
amount of ammo that can be carried for it
speed of followup shot
ability to penetrate cover
For me, this is for ranges out to no more than 100 yards, urban environment.
I would add to the criteria some additions.
ease of use (some rifles are not as ergonomic as others and hence are more efficient [slower] in bringing to bear and land shots on the target)
compact size (carbine, collapsible stock for easier storage and use in tight quarters)
