Chambered in 500 Auto Max, BHA’s groundbreaking AR500 Rifle is the most powerful AR firearm available. BHA was not content with the big bore cartridge offerings available in the AR platform, so the company made its own. The logical choice was something to match the power and versatility of BHA’s Model 89 Lever Action in 500 Smith & Wesson Magnum. The result was the development of the 500 Auto Max, a rimless 500 S&W Magnum to feed in a semi-automatic rifle.

BHA’s 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 an ATF-compliant pistol configuration: the AR500 semi-auto pistol.

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 over 55 different bullets ranging from 200grns to 700grns in almost any bullet type imaginable, including hard cast, jacket hollow points, monolithic solids, etc. This unprecedented range of bullet weight and design make the AR500 suitable for anything from prairie dogs to pachyderms to Peterbilt’s. Truck stopping power in a platform weighing less than 10 pounds. Factory ammunition for the 500 Auto Max is available through Buffalo Bore, Steinel Ammunition, Underwood Ammunition, and Defiant Munitions.

About Big Horn Armory:

Big Horn Armory was founded in 2008 with the expressed intention of designing a Browning-type lever-action gun chambered in 500 Smith & Wesson Magnum. The Big Horn Armory Model 89, made in America, closely follows the work of John Browning with refinements courtesy of modern metallurgy and machining capabilities. The first rifles began shipping in September of 2012 and since then, BHA has added to their big bore lineup with a Model 89 Black Thunder in 500 S&W, Model 90 Carbine in 460 S&W, the Model 90A in 454 Casull, the Model 90B in .45 Colt, the Model 89A in 500 Linebaugh and the Model 89B in .475 Linebaugh. In 2017, Big Horn Armory took a departure from its lever-action series and developed the AR500 Auto Max, the most powerful short-range, semi-auto based on an AR .308 platform.
