The only use I can think of is what little stabilization from recoil the stock can provide. It doesn't even help in concealing since you have to hide more gun in your pocket. It may not have much usefulness in airsoft but guns designed to look like other things are awesome! Like Megatron or the ARES from Robocop 2
