Nessie is a break-action, prime-on-break, Sillyshell-ejecting hand cannon. It is a large and sturdy blaster capable of performing higher than standard stringers, easily matching or exceeding 150fps using bottlenose shells.
Hardware-only option includes 4-inch "Slug" standard PT, 123 o-rings, 016 o-rings, rubber bands, small springs, lubricant, and pre-measured elastic. I have worked closely with LeedleDynamics to include elastic and rubber bands that closely match the metric products he designs around.
Pre-built option is the hardware variant for improved performance.
