PAB is our own variant of the ever-popular Caliburn (Capt Slug) and more directly the Talon Claw (Gabriel Gough), as well as inspiration from Argus Modworks. The design process came about mainly due to the lack of local sources for the original hardware, and our own preference for the blaster design.

PAB2.0 will use locally available hardware, which is slightly different dimensions from the original Caliburn hardware kit, hence will not work with PAB1.0. We have also optimized PAB2.0 to use LS (Long Shot) springs, which are more readily available in our part of the world, instead of the standard K26. However, a PAB2.0-K26 is also available should you want to use K26.

Alternative Hardware used:
3mm x 12mm aluminium priming bars
ID 35mm x OD 40mm Clear Tube
LS Spring
8x6 carbon fiber rods
M5 threaded rods
M5 lock nuts
M3 Aluminium standoff
ID 30mm x OD 33mm x Thk 1.5mm O-ring

*Note: This is for those with experience in Caliburn assembly. You can adapt the basic Caliburn assembly instructions and barrel shroud instructions to assemble this.

**Note: These are parts you need to print and replace in PAB1.0 to make it into PAB2.0, print the missing parts from PAB1.0 here
