Depending on method, I have no AR for sale but I do have BRs for sale. A method of Foam core poster board, hardened with plaster cast and carved out details with lights is RM150 but prices go up if requested add-ons like the lights and the magazine, and there is the NERF way, starts from a nerf recon, painted, RM170, confirmed price.
May I know how old are you?
