Why We’re Stocking This
When Big Horn Armory first launched the AR500 platform, we were skeptical like a lot of folks. Taking a massive revolver cartridge and making it run reliably in a semi-auto AR seemed like an engineer’s pipe dream. Then we got one in the shop, ran every kind of ammo we could through it, and our minds were changed. The AR500 NEXT GEN is the refined version of that—it’s robust, it cycles smoothly, and it solves a real problem for hunters in brush or for anyone who wants a formidable tool for demanding environments. We’re stocking the Big Horn Armory AR500 NEXT GEN because it fills a gap between standard large-frame ARs and more exotic, single-shot big bores. It gives a serious shooter a serious advantage.
The new Cerakote options are the clincher for us. This isn’t just about looks—though the finishes are sharp. It’s about durability. A firearm built for hard use in the elements needs a finish that can protect its investment. By offering these from the factory, Big Horn Armory is ensuring your AR500 NEXT GEN is protected from the ground up, and it saves you the time and cost of sending it out for coating later. We believe in selling guns that are ready for work right out of the box, and this upgrade makes an already tough platform even more resilient for our customers.
Who It’s For
- The Brush Country Hunter: If you pursue boar, bear, or large game in thick cover where shots are close and penetration through brush is key, the .500 Auto Max cartridge in the Big Horn Armory AR500 NEXT GEN delivers decisive energy.
- The Big-Bore Enthusiast: For the shooter who appreciates the physics of significant muzzle energy and wants it in a fast-handling, magazine-fed platform for sport or hunting.
- The Prepared Professional: For roles in security, forestry, or guiding in heavy predator country where a firearm must serve as an absolute last-resort tool of immense stopping power.
- The AR Platform Aficionado: For the builder who has everything and wants to push the boundaries of their AR-10 lower. The AR500 NEXT GEN conversion upper turns a familiar rifle into something entirely new.
- The Suppressor Host Seeker: With its large bore and substantial cartridge, the AR500 NEXT GEN is a naturally excellent host for big-bore suppressors, managing sound and recoil effectively.
Frequently Asked Questions
Q: Is the .500 Auto Max cartridge just a .500 S&W Magnum?
A: It’s derived from it, but it’s a distinct, rimless cartridge designed specifically for reliable feeding in a semi-automatic magazine. You cannot fire standard .500 S&W Magnum ammo in the Big Horn Armory AR500 NEXT GEN. Ammo and brass are made specifically for this platform, ensuring proper function.
Q: Will the AR500 NEXT GEN upper fit on any AR-10 lower?
A: It’s designed to fit most standard DPMS-pattern AR-10 / SR-25 / M5 lowers. We always recommend checking fitment, but compatibility is high. We can help you verify if you’re unsure about your specific lower receiver.
Q: How does the recoil compare to a .450 Bushmaster or .458 SOCOM?
A: The Big Horn Armory AR500 NEXT GEN in .500 Auto Max generates significantly more energy and, consequently, more recoil than those cartridges. However, the platform’s weight, efficient muzzle brake (or potential for a suppressor), and gas-operated action make it very manageable—more of a heavy push than a sharp snap. It’s stout, but it’s not punishing like a lightweight magnum rifle.
