Key Features

Reaches 225 F in 8 minutes, 450 F in 10 minutes, or 700 F in 14 minutes
  • Includes a flat top griddle insert and cast-iron grates for low and slow smoking or high heat searing
  • DigitalFan for precise temperature control
  • GravityFed Charcoal Hopper holds 16 lbs of briquettes or 10 lbs of lump charcoal for up to 10 hours of fuel
  • Convenient fold out storage behind side shelf to prevent loss or damage to the power supply
The Masterbuilt Gravity Series is transforming the way you grill with charcoal. This innovative digital charcoal grill + smoker delivers the classic flavor and versatility of charcoal cooking, paired with the ease and precision of a pellet grill. Its GravityFed design continuously feeds fresh charcoal to the fire, while variable-speed DigitalFan technology maintains your set temperature with accuracy, controlled directly from the intuitive PID controller or your smartphone.

In just 10 minutes, it can reach smoking temperatures as low as 225 F, or climb to 700 F in only a few minutes more for a perfect steak sear. The vertical charcoal hopper holds up to 10 lbs of lump charcoal or 16 lbs of briquettes, providing up to 8 hours of consistent cooking time. As gravity pushes fresh charcoal toward the fire, spent ash drops into the bin below for easy cleanup. For shorter cooks, simply insert the included slides to cut off airflow, extinguish the fire, and save your unused charcoal for next time. Enhance flavor by adding wood chunks either to the charcoal hopper or the ash bin to generate rich, smoky notes. Heat and smoke flow evenly through a precision-engineered manifold with graduated ports, ensuring consistent results across the entire cooking chamber. The main cooking area features cast iron grates and an optional flat-top griddle insert, giving you plenty of space and versatile cooking options for entertaining any party.

Great smoker!

I love my 1050, it does a great job on smoking and I love the heat it can generate at the drop of a hat (reverse sear ftw!).

It's the best grill I have ever owned.

I looked at a lot of grill over a year ago, price was not a issue but finding a grill that I could use several times without having to burn up a lot of charcoal was a issue until li found Masterbuilt . It depends on what I am doing ,using the big bag of charcoal I can get at least 4 cooking's out of 1 bag. Call me old school but these pellet grills in my opinion just makes the taste of the food to strong in flavor compared to charcoal whether it be hickory applewood pecan . That is one main reason I got the gravity 1050 grill.if you are a weekend griller you need to try one of the gravity series grills

Great grill, bad parts.

I had the 560 for about 3 years before upgrading to the 800. I loved the 560 and had no issues with it. I wanted more space so I upgraded to the 800. It worked awesomely for about 2 years and then the control unit gave out and wouldn't turn on anymore. I was completely disappointed because up until then the grill was amazing! I plan on fixing it though because there's honestly nothing like it for the price.

This grille is the best of every world

I bought this grille about a year or more ago. You can sear, grille, smoke and everything else in between on it. You can set it and monitor through the app via your phone. The only issue I've had is the controller went out that stopped me from moving the temperature up/down. But I was able to expense it and replace on my own (easy assembly) through my warranty.

The only fire starters for my smokers

I've got three MasterBuilt smokers — and only one fire starter that earns a place beside them. MasterBuilt's fire starters light fast, burn clean, and never fail. No gimmicks, no guessing — just pure, reliable flame every time. If you're serious about smoke, this is where your fire begins.

MasterBuilt 1050 -The Powerhouse of Smoke

I've owned both the Masterbuilt Gravity 1050 and 560, and let me tell you — these smokers redefine what it means to "set it and forget it." The 560 hooked me. The 1050 sealed the deal. Together, they've transformed every cookout into a full-blown smoke show. These machines aren't just convenient — they're commanding. The gravity-fed charcoal system locks in that deep, rich flavor purists chase for years, but with precision temp control that puts pellet grills to shame. Whether it's ribs slow-cooked to perfection or reverse-seared steaks with that perfect crust, the results are flawless — every single time. Cleanup? Simple. Heat-up? Lightning fast. Control? Effortless — especially with the app. What I love most is that they bring old-school charcoal soul into a modern world that's lost its patience for fire management. If you want the smoke, the sear, and the soul — this is it. The Masterbuilt Gravity Series isn't just a smoker. It's a statement.

Ham getting ready for the glaze and bacon wrapped carrots!   The best!

When will my item arrive?

Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we've all come to expect for small parcels, so it's important that you're prepared and understand what's required of you well before delivery day.

  • Most freight products ship on a pallet
  • Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
  • We'll specify which process you can expect in your shipping confirmation email.

For carriers that schedule delivery appointments:

Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can't be held responsible for damages that occur during delivery. As complicated as this process may seem, we've only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.

For carriers that deliver without an appointment:

Carriers that deliver without an appointment don't require you to be home or set up a delivery window, and you aren't required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you're home at the time of the drop-off, you can request the driver place your delivery in the garage; if you're out of the house, the driver will leave it near the garage or doorstep.

This item leaves our warehouse within 3-5 Business Days

30-Day Returns

Return all new, unused, and unassembled items in their original packaging, and we'll give you a full refund minus the cost of the original AND return shipping.
