Interesting you should mention 'bullpup', apparently some Cadet forces (are they forces?) chose them over the traditional BSA Meteor Cadet as the balance is very similar to the SA80 rifle. I had a Buccaneer a few years ago and thought it was great, the problem I found with it was that the thumbhole was too small for my hand, I could not get the correct 'straight back' trigger press as my thumb could not go far enough through to get proper alignment. The strange rigid foam stock will not tolerate modification as far as I know. The action can be modified for more power, if you get the shorter of the two Scorpion pistons and remove the buffer washer to long-stroke it and stick a more powerful spring in, you can get 8 or 9 fpe.
