hello,
I'm not building an AR, but I'm making drawings for another hobby project and I could really use good models of a .308 AR bolt carrier. It would be fantastic to have a model of the complete bolt carrier assembly.
Do you know where I could find such a thing? It doesn't matter if it's the DPMS or AR-10 standard, I'm not copying the dimensions directly, but it would be a fantastically useful reference.
