Last Updated On: October 30, 2025
Masterbuilt GS40 Gas Smoker
Buy Now Links

Masterbuilt’s 40″ Vertical Gas Smoker has large capacity with four chrome plated cooking racks that are approximately 22″ x 15″. Powered by a 15,400 BTU stainless steel burner, it features a porcelain coated wood chip tray and drip pan. The GS40 has two doors to facilitate replenishment of water and wood without opening the smoke box.

Many owners love these inexpensive BBQ smokers. Our posted MSRP from Masterbuilt is waaaay higher than the typical selling price. Check our Where To Buy section below to find this cooker for about half price.

Manufacturer Information
Masterbuilt logo

Masterbuilt is known for manufacturing low priced cookers, made in China for frugal people in the USA. They've always produced some models with a few unique features that provide a little bang for very little buck, but most of their products were largely more of the same cost driven stuff with a different logo on the lid. However, in recent years Masterbuilt has taken a step up in quality and innovation. In fact, some of their new products are starting to win our top awards. They are a company on the move, grabbing our attention.

Masterbuilt is widely distributed online and at brick and mortar outlets, including big box stores.
