Like new Radical Firearms RF-15 chambered in 5.56/233. Nice gun i took it in on trade but dont need it. This ar has the 12" fcr free float rail system(has top rail but can add more). The stock was upgraded to a magpul, come swith 1 30rd magazine. I was told this gun has never been shot and that appears to be the truth as i dont see any gunpowder and your typical factory oils. I am asking 750 obo i am also interested in trades let me know what you have but i am not interested in home builds
