You can’t go wrong with this reliable and powerful rifle that has proven itself over and over again. With its gas operated semi-auto firing action and chrome lined barrel, this rifle can perform efficiently and reliably.
One of the main perks to this rifle though is the ammunition. When the disaster happens, there’s likely to be few places to resupply if you haven’t stockpiled an enormous supply already, so the common .223 Remington ammunition that the M4 uses will likely be the easiest to obtain.
