right now i currently own a bushmaster ar-15 m4 receiver type XM15E2S with a 6position collapsible stockthe stock, pistol grip and hand guards are polymer,the rest is steel and aluminum , but for home defense the ar-15 round is a bit over-kill because of its penetration abilities are1/4 steel plate at 100 yardsa handgun or shotgun are more suited for this job.
