I've at least gone over 5k in my 10.5" rig. I've only had one breakage of any kind so far. That was a broken extractor (front lip snapped clean off). I think that was in my 10.5", but it could have been my 14.5"... I don't really keep any records (I know I should...), but that's all so far. I usually shoot suppressed, and my guns get pretty filthy. When you let the carbon bake in hard and then shoot full auto suppressed, it only figures you'll break something eventually. I'm too broke to go burning up cases of Wolf MPT lately though! Either way, I also keep extra bolts and pins in MIAD grips on my Grendels too. Bust something? No big deal, drop in a new one and let her eat.
