Hello, Cool project. I built a shooter Bladerunner Blaster a couple of years ago. I did a tutorial on the project and maybe something in it will help you.

I am currently building a second shooter but this time with a correct, real Steyr SL .222 upper with bolt, etc. The only difference is that this second shooter will have the accurate Steyr pieces and not a replica upper.
The machining of the Steyr upper is not for feint of heart! :-O
