JT ER2 long barrel

thingiverse

I designed an extended barrel for my JTER2, all by myself using Fusion 360. The new design features a small hole for catching the ball and fits perfectly on the marker without any additional modifications required. I've tested it with a few practice balls and even dropped it once on hardwood flooring with zero damage. It's unclear whether this upgrade will improve accuracy or FPS performance, but it does fit snugly in place.
