Weapon Extension Exploit Framework
Example platform to demonstrate the ability to use the weapon extensions to have a workaround to the cannon deadzones extending the barrel of the gun through a 1x1 gap allowing for better "fit" visually of barrels for designs specifically but not limited to the Bertha and Artillery, and light autocannon, using the battle cannon as a base "extension."
Top cannon is an unmodified model, bottom is the adjusted variant.
Notes
Any cannon barrel can be replaced with another barrel excluding the machine gun which cannot be extended.
The length of the non-native extension(s) will be subtracted from the true barrel length resulting in the firing animation as well as bullet spawn zone to be displaced into the barrel of the gun, This is usually not an issue in terms of collision.
