Nerf Strongarm 10 Shot Brass Cylinder

Brass barrel cylinder for the Nerf Strongarm.
This is untested and may not work as intended!
This needs brass barrels in order to work. I have included the brass size and lengths below in both metric and inches.
Metric:
Needs ten 62.5mm lengths of 13.5mm brass.
Total of a little under 0.63 meters of 13.5mm brass tubing.
Inches:
Needs ten 2.46" lengths of 17/32" brass.
Total of a little under 25 inches of 17/32'' brass tubing.
