Why We’re Stocking This
We decided to bring the Big Horn Armory AR500 NEXT GEN into our inventory because it solves a specific problem for a specific kind of shooter—our kind of shooter. We handle a lot of firearms, and the gap between a hard-hitting .450 Bushmaster and a traditional large-caliber bolt gun has always been noticeable. The AR500 NEXT GEN fills that gap with engineering excellence. This isn’t a novelty; it’s a robust, well-thought-out system. We’ve handled the platform, felt the solid lock-up, and seen the quality of the machining firsthand. Big Horn Armory didn’t just slap a big barrel on an AR-10; they engineered the AR500 from the ground up to handle the significant pressures and unique feeding requirements of the .500 Auto Max cartridge reliably.
For our customers, this means access to a tool with unparalleled authority in a semi-auto package. We stock it because we believe in offering tools that represent the cutting edge of their category. The new Cerakote options are just the icing on the cake, allowing an owner to add a layer of personalized durability. In a landscape of similar-looking rifles, the Big Horn Armory AR500 NEXT GEN stands apart as a serious instrument for serious tasks, and that’s exactly the standard we hold for the products on our shelves.

Frequently Asked Questions
Q: Is the .500 Auto Max cartridge hard to find, and can I use regular .500 S&W Magnum ammo in it?
A: This is a crucial distinction. No, you cannot fire a standard .500 S&W Magnum cartridge in the Big Horn Armory AR500 NEXT GEN. The .500 Auto Max is a rimless version designed specifically for reliable feeding in a semi-automatic magazine. Ammunition is available from specialized manufacturers like Underwood Ammo and Buffalo Bore. While not as common as 5.56, it is readily available for those who seek it out, and we can help source it. This is a dedicated platform for a dedicated cartridge.
Q: How does the recoil compare to a 12-gauge slug gun or a large bolt-action rifle?
A: Having fired the AR500 NEXT GEN ourselves, we can say the recoil is substantial but very manageable due to the platform’s design. The semi-auto action, combined with a good muzzle brake (often standard) and the weight of the rifle itself, spreads the impulse out. It’s a strong, deep push—more of a shove than a sharp snap. It is noticeably less punishing than a lightweight slug gun and, in our experience, more controllable for rapid shots than a heavy-recoiling bolt action in a similar class because you don’t have to manage the bolt.
Q: I have a DPMS-pattern AR-10 lower. Will the AR500 NEXT GEN conversion upper work on it?
A: In most cases, yes, the Big Horn Armory AR500 NEXT GEN upper receiver is designed to mate with standard DPMS-pattern AR-10 lower receivers. However, we strongly recommend a consultation. The .500 Auto Max generates significant force, and ensuring your lower’s buffer system and overall build quality are up to the task is important for reliability and longevity. We can inspect your lower and recommend any necessary components, like a specific buffer spring, to ensure a perfect, safe marriage.
