AR500 – 500 Auto Max



The AR500 is an AR rifle like no other.  Chambered in 500 Auto Max, our ground-breaking AR500 Rifle is the most powerful AR firearm available.  We were not content with the big bore cartridge offerings available in the AR platform, so we made our own.  The logical choice was something to match the power and versatility of our Model 89 Lever Action in 500 Smith & Wesson Magnum.  The result was development of the 500 Auto Max, a rimless 500S&W magnum to feed in an semi-automatic rifle.  Our bold AR design and big bore 500 Auto Max cartridge put an unparalleled amount of power into a pleasant shooting, rapid firing, versatile rifle.  This combination of size, familiar manual-of-arms, available accessories and energy on target make the AR500 Rifle ready to handle almost any situation.  The AR500 is also available in a braced-pistol configuration!


The 500 Auto Max is a rimless 500 S&W Magnum that is easy to obtain or reload. A very versatile cartridge, It can be had in loaded ammunition with bullets ranging from 350grns to an amazing 600grns.  The handloader can utilize bullets ranging from 275grns to 700grns in almost any bullet type imaginable, hardcast, jacket hollow points, monolithic solids, etc.  This unprecedented range of bullets weight and design make the AR500 suitable for anything from prairie dogs to pachyderms to Peterbilts. Truck stopping power in a platform weighing less than 10 pounds.
