What we have learned: Our Bolt Carrier Groups are better. Why? Because we haven't had any returns. We are not seeing the early degradation that is prevalent on other bolt carrier groups and coating. Because our BCG's have minimal tool marks and virtually no tool marks on the lands, they tend to run smoother and quieter than those with visible tool marks on the BCG lands. And they also look better without the tool marks
