Yes, but my 4 Mini-14/Ranch Rifles has never given me any functional problems with comercial ammo. Accuracy is good to have but reliability is must on any rifle.
As you can see I'm a Mini-14/Ranch rifle fan and have been for about 15 years. I been playing with AR-15/M-16 for only about 4 months now. Still have much to learn.
As to replacing my Mini's with AR's... time will tell but it won't be any time soon.
