About Big Horn Armory:

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 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.

The gun AND ammo are WAY OVER PRICED ! Build a .50 Beowulf or .458 SOCOM upper for your AR15. You can also build a .450 Bushmaster or .350 Legend and others. some states requires a STRAIGHT case for hunting,so check before you build or buy, the SOCOM may not be legal. I did the Beowulf, about $27.00 (some less some more) for 20 rounds of Alexander 335 gr. ammunition, or $1.35 per round. You don’t have to buy and AR10 (upper and lower to build) or specific $2,000.00 Big Horn Armory gun….More shooting for less money. Shoots great, more… Read more »


You also have to have the AR10’s mag well modified to use a smaller AR15 magazine in the bigger well…


The current price of this ammo is $2.20 per round. Interesting but no thanks. I have enough calibers already.
