hey guys me and my curious mind was looking around on the web and i didn't come across very many bullpup's that are AR-15 based, and the ones that were required allot of permanent mods and large changes to the operating system. so i took up the challenge and tried to create a drop in bullpup design for real steel or GBBR's (possible with aeg's but is a bit different design). im not decided on weather to use a wire system or cable system for the trigger. i decided that i dont want to use an electronic trigger because then i would need to carry a battery with. if i get some good plans drawn up on CAD i might try building a prototype in real life. i have access to a machine shop, CNC, and rapid prototype machine 3D printer(last 2 through school). so building it wouldn't be too hard of a problem. give me some input and share your designs. Design 1.0 theres a pad around the buffer tube and on top of the rail. in this design it uses a wire attached to the trigger, attached to a pulley, attached to a cable, attached to the original trigger. the stock will be more stream lined but i couldn't find anything on pimp my gun that matched.
