Certainly, all of my kit is my real steel kit. If you are going to use a plate carrier, I'd suggest removing the plates and replacing them with carpet or foam. No sense in carrying the extra weight, and plate carriers don't wear very well without something filling them out.

Honestly, there isn't much use for a light or optic or all the rest of the tacticool rifle mods in AS. The projectile just doesn't really lend the platform to enhancements. But, as a lot of AS is about fashion, and you like all the gun bling, bring it
