I have a question. My son fell in love with the look/feel of the AEA Challenger Bullpup that he saw at the raffle at RMAC. I must admit that the wood thumb-hole stock with built-in bag-rider is pretty sexy, but I really don't like the rear cocking lever and the fact that it isn't regulated. I would like to get him a gun that he likes and can be competitive with. I'm thinking that it is a bad idea to try to upgrade the Challenger to compete because I will probably have to start with a new barrel and go back from there, so I will basically just be keeping the stock and maybe the trigger and I am still stuck with the cocking lever unless I do something really drastic. I would prefer to start with a better platform that has the forward cocking lever, at least. I would prefer not to have to replace the barrel, and valve, etc. Sure I can re-port the system if I have to, but is there a platform that is more "bullet-proof" and ready for competition that has a nice wooden thumb-hole stock? Thanks so much for the insight!!
