The most difficult part was fitting Asiatam's elevation/recoil unit inside the turret, while reshaping the mantlet to the correct size and position.
The new gun barrel is made in metal, two parts, one sliding into the other.

Inside the barrel I fitted the muzzle flash led from Blitz, while the warning led was replaced with the IR emitter for the DBC unit.

After a lot of filing and testing of clearances and movements, everything found its place. I also had to repair a small micro inside the recoil unit which came already stuck from the factory.
