Firstly, could one, hypothetically, attach an electric motor that had a gear on the end of the drive shaft which had teeth similar to that of the priming mechanism so that the blaster could be automatically primed? This combined with a trigger mech and push to off switch could make the priming and firing of the blaster a one stage process, rather than a two stage.
Secondly, as Informer has done with silicone tips, could a silicone pellet be made which had the same overall dimensions of a paper pellet? This would make the pellets re-useable and remove the need to add BB's to the paper ones.
I am currently trying to get hold of a one of these blasters to see if either of these ideas are feasible.
