Okay being a gun lover and something of a student of physics and machinery. I have to ask....what's up with the rotating cylinder just above the box magazine? I don't understand? Is that a secondary firing weapon? By your gun physics the magazine rounds should be feeding up into the bolt and locking mechanism to be chambered and fired yet that rotating cylinder would get in the way? Please don't get me wrong or think me a troll gnitpicking I love your guns and I've favorited them. Just curious from a gun lover point of view. I hope to hear from you.
