Hi Readers, well what can I say. I bought these Heavy Gauss Cannons in the height of 'Failcast' epidemic, they were bad... then sat in the closet of doom for years until I did some research. I saw this Heavy Gauss Cannon Conversion on You Tube, and also have now seen this conversion if you really want chunkier guns! Its a great Necron Blog "BoneCron", check it out - Necron Heavy Destroyer Conversions, but I never have spare Immortal Gauss Blasters, but what I might have is spare Tomb Blade Gauss Blasters - so I made the following.
Hope you like this. No need to purchase the wonky 'failcast' until GW makes them straight and in plastic.
