3. They are most likely using 4140 because it's been Nitrided. Let's face it, you said yourself they are building it as an entry level gun. Ruger really doesn't know how to build a good AR so it's no surprise.
I don't know about not knowing how to build a good AR. The gun is sixty years old so it shouldn't be too hard to find the info and/or find someone to hire who's been previously involved with manufacturing AR's for military use.
Just seems odd that 4140 would be used on this rifle when the piston gun line uses 4150. It would seem logical that the two rifles would share as many common parts as possible. Now granted I'm not up on current production. Possibly the latest SR556 has a 4140 barrel.
I suppose the decision is an economic one. 4140 is probably less expensive?

“The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles."
