The new internals feature PETG rebarreling (complete with the auto-rotation), a Hornet AS-6 air tank and tubing replacement, an improved seal, and a glued trigger spring.
The paint job was added after the original modification. soloz1 says this about the paint job:
The paintjob includes a black vinyl dye flat-black base coat, pink and green folkart detailing. Unfortunately, this blaster is no longer in service. I hope to revive this fun project one day.It's a shame that his AT3K no longer works, as soloz1reported that the blaster's firing ranges were between 70 and 110 feet. Very very impressive! It makes me wish the blaster still worked.
