Hey all so this post is very picky. I am looking ONLY for an m16 Scarface by g&p with the nade launcher, or an m4 like the picture, but I does not need the m203. It must be a long barreled quad rail m4. No shortys, key mod, etc. prefered full metal as well, although I am looking at the specna arms model. Please let me know. Just the externals are ok, and an m203 is a bonus.
