The big horn armory ar500 has amped up the cartridge to a serious big game hunting rifle cartridge. Chambered in 500 auto max our ground breaking ar500 rifle is the most powerful ar firearm available. The ar500 is an ar rifle like no other. You ve never heard of this cartridge because it didn t exist before big horn armory began developing the ar500.

The big horn ar500 500 auto max can effectively harvest any animal. Specifically big horn armory uses an 18 pound recoil spring and a 3 8 ounce buffer. It is difficult to compare the bha ar500 pistol to any other cartridge and platform combo on the market. We like to think big at big horn armory.

Being a rimmed cartridge isn t well suited to box magazine fed rifles. Obviously the bolt has to be altered as the new rim on the 500 auto max is a nominal 520 inch in. Big horn armory has created its own ar sub category with the ar500 chambered in 500 auto max. This combined with a mid length gas system and an in line muzzle brake makes the ar500 manageable.

The result was the 500 auto max a reduced rim 500 s w currently available loaded.

Whether it s packing 36 800 ft lbs of energy in a lever action or building the. We were not content with the big bore cartridge offerings available in the ar platform so we made our own. Felt recoil is still rather stout maybe on par with shooting 3 inch magnum shells out of a 12 gauge pump gun but not joint busting. So big horn armory started with an ar 10 and the end result is a rifle it calls the ar500.
