Description
Picture this: you’re in a Missouri hardwood bottom, the sun’s low, and you need a round that can punch through brush and deliver decisive energy on a hog or a whitetail at 150 yards. You need a modern, hard-hitting brush gun that doesn’t sacrifice the ergonomics you’re used to. That’s the exact scenario where the Black Rain Carnivore 450 Bushmaster, 16″ Barrel, MOE Stock, OD Green Cerakote, 10rd shines. I’ve put a few boxes of Hornady Black through one, and it changes the game for close-to-mid-range hunting in our terrain.
Answer Capsule: The Black Rain Carnivore 450 Bushmaster is a purpose-built AR-platform rifle chambered in the potent .450 Bushmaster cartridge. It features a 16-inch barrel, a Magpul MOE stock, and a durable OD Green Cerakote finish. Designed for reliability and power, it’s a modern hunting and brush gun that ships to Missouri and compliant US states.
Let’s talk about that chambering first. The .450 Bushmaster is a thumper. It’s a straight-walled cartridge that’s legal for deer in many states, including ours, and it delivers energy similar to a .45-70 Government but from a familiar AR-15 platform. The 16-inch barrel is the sweet spot—it keeps the overall length manageable for moving in a blind or through thickets without giving up too much velocity. The rifle comes in at a solid 7.8 pounds unloaded, giving it a stable, planted feel that helps manage the substantial recoil impulse.
The build quality is where Black Rain makes its name. The upper and lower receivers are machined to tight tolerances. I found the fit to be excellent, with no wobble, and it’s mil-spec compatible where it counts. This means you can swap out the MOE stock for your favorite B5 Systems or Magpul CTR if you want, and the handguard accepts standard AR accessories. The OD Green Cerakote isn’t just for looks; it’s a tough, corrosion-resistant finish that stands up to humidity and field use. The rifle uses a dedicated .450 Bushmaster bolt carrier group and a heavy-duty buffer spring to reliably cycle the big rounds.
Magazine capacity is 10 rounds, which is plenty for any hunting situation and aligns with regulations in various jurisdictions. The included Magpul MOE stock and pistol grip provide a solid, comfortable hold. The rifle runs flawlessly with factory ammo from makers like Hornady and Federal. At $1347.57, it’s positioned as a premium, ready-to-hunt package. You’re paying for a rifle that’s assembled with attention to detail, not just thrown together.

Pros & Cons
The big pro is obvious: it delivers serious power in a familiar, customizable platform. The build is robust, the finish is durable, and it’s drop-in ready for optics and lights. The cons? Well, .450 Bushmaster ammo isn’t as cheap or ubiquitous as 5.56, so factor in practice costs. Recoil is stout—more of a big shove than a sharp snap—so it’s not a plinker. That said, for its intended role, it’s incredibly effective.
Who It’s For
This is for the Missouri hunter who wants a legal, modern rifle for deer or hog in thick cover. It’s for the shooter who appreciates the AR platform but needs more downrange authority than .223/5.56 can offer. It’s also a solid choice for someone looking for a capable, short-range defensive rifle against large predators. If you’re stuck choosing between a traditional lever-action and wanting modern features, this bridges that gap perfectly.
Frequently Asked Questions
Q: Will this rifle work with my standard AR-15 magazines and lower receiver?
A: No. The .450 Bushmaster requires specific magazines due to the cartridge’s larger diameter. This rifle comes with dedicated 10-round magazines. The lower receiver is a standard AR-15 pattern, but you must use a dedicated .450 Bushmaster upper, bolt carrier group, and magazines for safe operation.
Q: Is the .450 Bushmaster a good deer cartridge for Missouri?
A: Absolutely. It’s a straight-walled cartridge that meets the requirements for certain hunting methods in Missouri and delivers excellent terminal performance within 250 yards, making it ideal for our wooded and agricultural landscapes.
Q: What optics do you recommend for this setup?
A: A low-power variable optic (LPVO) in the 1-6x or 1-8x range is an excellent match. Brands like Vortex, Primary Arms, or Leupold offer great options. A robust red dot sight is also a fantastic choice for fast shots in dense cover. The rifle’s Picatinny rail gives you plenty of mounting options.
