Doomsday preppers and survival enthusiasts alike are constantly seeking the best firearm for each scenario. When you’re looking for the perfect “crap” hits the fan (SHTF) weapon, several factors need to be considered in order to maximize the odds of survival.

Building a complete survival kit should include an adaptable firearm that can be handy in virtually any situation. Today, we’ll look at a few benefits one can utilize when it does hit the fan.



In any doomsday scenario, the need for a reliable weapon is key for survival. Being able to hunt for food and defend yourself is a major consideration. While the M16A1’s gas operated design led to a high malfunction rate, today’s modern military and civilian variants hold a proven track record. As long as all of your parts are up to spec and everything is cleaned regularly, everything should function when that trigger is pulled. The AR-15’s prevalence in society and heavy usage has worked in tandem to produce a product that performs better than average and exceeds the standard for civilian firearms. Purchasing our upper and lower parts kits can provide years of reliable service under strenuous situations.




Most preppers will agree that the prevalence of ammunition in an apocalyptic world is key for survival. While your unique rifle caliber may be useful in specific scenarios, it can come back to haunt you when ammo becomes scarce. The best firearm is nothing more than a fancy club when the clip or magazine cannot be fed. Utilizing our .223/5.56 rifle kits can pay dividends when it comes to the prevalence of ammo. The military’s standard use of 5.56mm and the civilian preference for .223 caliber rounds makes the standard AR-15 a top choice in the United States. For those looking to use a larger round, our .308 caliber 80-percent lower receivers can be purchased for easy convertibility on your rifle. This civilian version of the 7.62x51mm NATO round has long been used in hunting and competition shooting and also comes in high supply in the US.



While this term is not the most accurate, it does encompass the importance of being able to replace parts that may break during use. With the high volume of AR-15’s in our country, being able to find spare pieces should be much easier when compared to other firearms. The National Shooting Sports Foundation has estimated that US citizens own between five and 10 million AR-15 rifles. With this in mind, it’s easy to see the value of owning such a weapon in this neck of the woods. The alternative would be machining your own parts, a process that requires the equipment and expertise that may of us do not possess. From neighbors and sporting goods stores to your neighborhood police station, chances are that AR-15 parts will be your best for replacing broken pieces and regaining defensive and hunting capabilities.
