I have a brand new never fired Evike Chrono Blaster (the MA5B Assault Rifle from the Halo video game series) I just received it and have never used it and am looking to get around $500 OBO, would prefer to Exchange for for one of the following Falkor REECE/BLITZ, SAI GRY, Krytac MK2 SPR/LVOA, or a VFC SCAR/AVALON/MK18, OR any high tier M4 platform
