I didn't see a subject title for talk about "other types of weapons" so I hope this doesn't seem like blasphemy here. But since XCR enthusiasts obviously tend be a discriminating bunch I'm looking for some opinions on bullpup type weapons. I'd like to own one if there is one that particularly stands out as a worthy consideration. I've looked at FN Herstal. Steyr, and Kel-Tec, but I need to know about any others that might be out there, that you can actually buy in the U.S. that is. I understand the concepts of shorter profile/longer barrel, different balance, and those types of things but I need to know more about the reputation and reliability of any particular weapon or manufacturer as well as any tactical advantages/disadvantages that this configuration brings. I feel like I have the best conventional style weapon in the world as far as the XCR, so I'm just looking to diversify my collection. Thanks.
