Features that make charging handles nice to use are being large enough to grab on to, having texture “should your hands get… wet,” and having a concave shape that a finger naturally fits into. These three features make it far easier to use, particularly during training when hands get sweaty. Unfortunately, to achieve all of these features is difficult, complicated, time consuming, expensive, and requires a very capable machine to do it properly. There’s a reason why there are no charging handles with all of those features… until now.
