Early work on Sister of Battle bolter.
Whole bolter will not be simply scaled up from miniature, it will be of more reasonable size, with it's true caliber from sources (.75" / 19mm). This is an idea of less comically proportioned bolter:
Fleur de lys front sight is a must however as I used on her pistol.
Got broken AK mag (it cost me whole 0.5$) and made rough base for bolt shell:
Had to ground mag feed lips to fit bolt shell. Since mag will be removable I had to make it look full.
What I will NOT be doing - side-window on a mag - local AK mags are made of thicker and harder steel than most other, so this would be quite hard to do. In that case I would also have to make at least 10 shells so I decided to scrap that idea.
What I will do - fleur de lys on both sides, possibly purity seal on right side. Rivets. Paint the fucker.
I also got one of those grips to use on it and to shorten time needed (good grips are a cast iron bitch to make from scratch):
Rest of bolter will be made from scratch.
I am also considering mounting laser sight (cheep laser pointer) and putting some cheap knockoff airsoft optics on it with some mods to fit better to 40k style.
