Nerf 70mm Mega Hammershot Cylinder

thingiverse

There are two cylinders available here, each designed for specific types of barrels - one for 15/32 barrel material, likely brass, which provides a loose fit that's not so loose it causes megas to come off, and another for 1/2 barrel material, potentially aluminum or brass, offering a tighter fit. Deciding between them can be challenging. It's crucial to carefully glue the spigots onto the cylinders in a straight line, ensuring there are no gaps through which air can escape. The cylinders can support up to 70mm megas, though some trimming around the front post may be necessary. The spigots have a maximum length of 56mm, including the portion that needs to fit into the base of the cylinder. If desired, you can even use shorter megas. Darts can technically fire with stock springs, but an upgrade spring will likely provide better performance.
