I wonder why they are not more popular. Yes, lefties are bubblegummed on some designs like my HS-10B shotgun, but with all the emphasis on compactness for CQB I would have thought bullpups would be all the rage. I've always been a fan of the bullpup design even some that weren't done quite right like the Bushmaster pistol I used to have. It worked fine, was compact, but the sights were worse than a Sten gun with the canting pistol grip and all. The Steyr AUG was my favorite so when MSAR came out with their clone I was very happy when the prices began to be reasonable. I thought about going for broke and getting a PS90 cause I love Stargate and all but I couldn't see going to a less powerful yet more expensive caliber. I still may get one or at least an airsoft... First the H&K 416 was all the rage cause it was a piston M4 and made by Germans. So everyone started pulling piston designs out of the patent office archives. Now the SCAR and MagBush ACR are new kids on the block. I really don't get it. The stg-556 is a piston system proven for over 30 years, it has a scope, I can rail it if I want and its a full 20 inch barrel with the same length as an SBR'd M4. The manual of arms is a bit quirky. The only real life disadvantage I see is Pie'ing off a corner where normally I would switch hands on an M4. You can do it with the AUG but it looks ghetto so to speak. Oh, I've seen vids on youtube where they have bullpupped a Saiga 12. What do you guys think of various bullpup designs like the FS2000, Tavor, Bushy M17S, Chinese AK thingies...? Show your collection if you have any.
