I'd like to hear more about them.The gas system could be better,it lets some gas past the piston and that fouls things up and the gas system isn't optimal for a suppressor.The short length of bullpups makes them ideal for one though.One of the reasons I've read why not many people have one is they don't make many and the distribution system isn't good about the consumer getting a good price.I've read that with the LSAT testing that a bullpup rifle might be the next military rifle using caseless or telescoping ammo with a pivoting chamber like the HK G11.Weight and size could be reduced by a third or more.One of these days I'd like to get a bullpup but they aren't perfected yet it seems and overpriced.I'm surprised that somebody like Freedom group hasn't bought into the bullpup rifle.They got into most everything else.
