its funny you ask about the nfas. when i began modeling it, i started with a 2d image. as it unfolded, i started shaking my head by the poor modeling job the original designer had done on it, but never noticed the details, or lack their of until this project. it appears to be a mashup of a few weapons. part ak, part ar, part nerf gun. the theme was all over the place, but it didnt share any common design features with anything i know of in existence. if it is the usas-12 that was the inspiration, the designer took a lot of artistic freedom with his version...... i plan on building a real life version on the nfas, but i needed to start with existing gun parts that are easily available. so if you pay attention to my model, youll see ar and ak components to scale. the model was never 100% finished, it still needs alot of design configuration changes to make it functionable, but this was a spitball of ideas i had been kicking around and i was happy with the direction it went in.
edit, for the record. no, it will not be automatic. just saying.
