The lack of a FA does not make the Sport low end, lots of AR's with one are low end. However the lack of a dust cover does make the Sport low end or a hobby gun i.e. not a firearm I would select for self defense or survival use.
I'm going to disagree with this statement as well. An AR-15 without an ejection port cover is perfectly capable as a self defense / home defense rifle. Are you dragging it through sand, mud, and muck as you go down the hallway to see what the dog is barking at?
As far as survival, mine has ridden in the back of the pickup, on a rack on the jeep, and on a rack on the four wheeler while running around a ranch in west Texas. The thing gets filthy, covered with red dust and dirt, and dust from the gravel roads outside the fence.
Even with all the dust and dirt, my Sport has never let me down. When they first came out, there was an article about testing it at Gunsite, and the author was throwing dirt into the action to see if he could force a stoppage, and never did.
I wouldn't mind an ejection port cover, but I haven't experienced a failure caused by not having one.
