I'm having my M16 upgraded to 500fps with 20's, but it'll still have the capability to shoot full auto when it comes out of the shop. Will I be able to use this at a field before having it made to semi only? It's probably a "duh" question, but it's something I would like to know for certain. I'll probably end up putting a 120+ spring in it, leave the other internals upgraded, and keep my full auto. Would that be best?
