Agreed but not $400+. I like Colt, DD, and FN BCGs. You can burn them down and they'll still run. I like Toolcraft too because they are like one Ben and you can wear them out too. Not like a Colt, but you can run them.That is pretty funny but the bolt is a major item in any AR, so if your depending on the rifle to keep you living maybe going a little over budget is worth it.
I have two...I like them a lot but they aren't so full auto. We ran them in my old job and pulled them from our guns. Great for semi. I still use them, but Enidine buffers don't exist anymore. Kyntec is the new hydraulic buffer company now; they look just like Enidines.Here is a picture of my ENDINE Fullauto AR Buffer.
