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.

Love my gravity smoker!

I bought my Gravity Series 800 about two years ago and have loved every minute of it. My smoking journey began with propane smokers. Will never go back! The fun and favor of cooking with charcoal and wood is unbeatable. The ease of use of the Gravity Series makes this approachable for folks of any skill level.

Jack of All trades master of all

I have been using this for the last 18 months and it has been the best grill and smoker I have ever had. I use it several times a week year round. It holds up well. One of the other great benefits is the modularity. I had an issue with chimney, I was able to replace that piece with ease instead of having to purchase a new grill or the full chimney. Amazing product

Fred;s fuel

Over time I've used the Masterbuilt lumps and starters have no issues, they both have worked great. My only issues is like all others by the time you get the lumps you have alot of smaller pieces due to shipping. But that's with every other lump product out there.

Best Fuel

I also use wood splits a lot but hands down as a standalone or combo wit the wood this gets you the best burn without adding bad flavor.

It works!

Just simply, it does what it is supposed to do, keep the grill dry. I have not had any dry rotting issues either.

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

$49 Flat-Rate Shipping

Anything under $49 ships at one low price. If your order increases, your shipping stays the same!

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.

No Restocking Fee

Most companies charge a restocking fee. We just don't do business that way.
