TLOJ is a simple pull-to-prime blaster that provides two options for barrel orientation. You can reconfigure it to resemble a Jolt, or replace the Topper to configure it to shoot out of the plunger. The other peculiar feature of this design is that it requires no tools in order to be assembled. All rotating components use nylon spacers as hinge pins which slide and lock into retaining printed features. The plunger assemble is a self-retaining assembly that is held together by the components being assembled in sequence.
The design will later be updated to include rail mount options, alternative breech options, and an RSCB setup.
