As of yet, I have not seen reports of these failing to begin with. However, aftermarket manufacturers, tactical dealers and hard core enthusiasts on the inter-web have done a good job of convincing some that their AR's aren't worth a damn unless they re-build the thing with parts that would make a complete build cost $4000.
Depends on how its being used.
Typical user is going to go out 6-9 times a year and run 50-150 rounds each session. For such people anything will do even the most shoddy dpms/bushmaster out there. They serve just fine for such things as well as home defense.
For the person that goes out and pops off 5000-6000 rounds on a prairie dog shoot a properly made shot peened mpi inspected bcg with a carpenter steel bolt is probably a necessity and they probably still take a spare.
Same is true for someone that goes to carbine classes frequently.
Then there are folks that have experienced hell on hunting trips from cheaping out and something critical breaks. I fall into that category. Im done spending several thousand on a vacation hunt with the wife only to be sidelined in the middle of nowhere forced to use a backup gun because i cut corners on gear.
You dont have to get the best you can but if your depending on it to function its a good idea to minimize the risk of failure and a ruined outing.
Just my experience with lowend firearms optics and gear
