Cerceus Pattern Bolter

Concept art (shamelessly borrowed from whomever did the original mockup) for the Cerceus-Pattern Bolter I'll be using with my conversion project.

The Cerceus Pattern bolter places the barrel more in line with the charging handle.ejection port, flipping the auto-sense targeter link

underneath the barrel. This allows for greater ammunition capacity, and a simplified internal mechanism. Front sight post has been shaved down since it had no corresponding rear sight anyway, and was thus non-functional. Instead the top cowls conceal flip-up auxiliary sights in case the Marine's helmet is disabled.
