I own an Ops Core Fast SF Super High Cut Ballistic helmet and also an Ops Core Fast SF Bump helmet. I'm running ActInBlack DTNVGs on a Wilcox L4 G22. I'm wondering if that amount of movement I'm getting between the Wilcox and ballistic helmet is normal? The mount locks up very securely in the bump helmet, with only a little bit of play. But on the ballistic it seems excessive. Going to try and attach videos to demonstrate what I'm talking about.
