I do not want to post this as it is now part of my version of I_am_canadian's cannon v2. However, I have posted a slideshow to show you all that I do actually sometimes build something! Credits to theDunkis for the mag. I find it sturdier and more accurate than Trauts' one, but less powerful.
1: The gun. Pink socks!
2: The adjustable sight. Slides the whole length of the rail.
3: FPS view through the sight. With forward iron sight also.
4: The mag, hinges used so the sides flex slightly, allowing it to be clipped in easily.
5: The stock and butt. Removable, with cheekplate in line with the sights, and a flexible butt.
