...for serious defensive use it fails one major criteria badly
No iron sights...
Why oh why do they keep making rifles that don't have an option to get some iron sights? Not every shot made with an all purpose rifle is going to be at 200+ yards.
Does anyone know if there is a way to add fixed sights to a rifle that doesn't have them? I've heard of converting sights but never just adding sights where there were none before.
