Caliburn faux barrel extender

This is a caliburn barrel extension meant to be used with a 25mm (aluminium) barrel.
this kit contains both a way to mount this 25mm tube on your caliburn and 'sniper' end cap for that same tube.
This is a wider faux barrel to hinder the dart as little as possible, for that reason use a 25mm tube with a smooth inner surface. The original 'real' caliburn barel also sits completely at the top of this much bigger barrel so that you cna benefit of the extra width as much as possible.

there are multiple versions depending whether you want to use a longer or shorter barrel and thus need more or less support. The 'short' and medium versions are fit for a barrel not much longer than the printed part itself, the long ones can hold a much longer tube.

If you are looking for just a barrel extenson cap without needing to insert a metal tube see here: https://www.thingiverse.com/thing:3678131

If you are looking for a barrel extension to cover a real long barrel (because of a very high spring load) look here: https://www.thingiverse.com/thing:3685439 but this barrel would work for that purpose too, it can cover a real barrel just as well as no barrel ;)

Can be printed without supports, you will only need to remove some messy filament in the hex nut holes.

You can add screws on the bottom and the sides if needed, just drill a small hole in the connecting plate and you can screw it on.
To fixate the tube use some superglue
to fixate the end cap add 2 screws in the bottom holes

All rights for captain slug since it all a remix of his original design

Update 19/01/2020 added a new long version with a bottom rail so you can add a bipod to the barrel extension. This version also incorporates Captain Slug's barrel screw system from the caliburn so you can now fixate theis extension on the aluminium barrel with a with the same screw and nut from the caliburn hardware kit.
