I did three sketches of rifles for a project. The one I choose must be a remember of our actual rifles but enough different to not be able to say "ey, this is an M4, or this is an AK47....."
The feeling of the gun must be a good rifle capable of overcome all the enviromental changes and situations (maybe like an AK, for example), I mean, a really reliable rifle.
This is the three sketches, I donīt like the number 3 because is too complicated in the design and I wanted something more simple. But maybe you could make me change my opinion. What of these do you like for this purpose??
