Well I've had this idea to take a magstrike bladder and pump and hook it up to a friefly, you know that rod that goes under the handle,well,you could put the pump there,the take out the spring and all the fireing stuff and replace that with the magstrike part that blows the air out, and then just plug up 1 of the two holes, then hook it up to the revolving part(the barrels) and make it somewhat air tight. Then use the original trigger to rotate the barrels and put the trigger that'll shoot the air to the barrels. But don't hold down the triggger suppling the air too long or you'll have to pump it alot and make that all some how work PLZ DON'T BE TOO CRITICAL OF MY CRAZY IDEA,just think you could get a firely to go alot futher vs. the spring used in it. P.S. I edited it nd nice picture.
