Piston Gravity Bong MJ Arsenal

The MJ Arsenal Piston Gravity Bong is a modern, all-glass device that uses water displacement and air pressure to deliver powerful hits, enhanced by a first-of-its-kind integrated disc percolator for smoother smoke. It is constructed from 100% borosilicate glass, thick and durable, and it’s inspired by the home-made pop bottle gravity bongs.

Key Features

Disc Percolation: Unlike traditional gravity bongs, the Piston incorporates a disc percolator to filter and cool the smoke as it passes through the water, reducing harshness.

Gravity Slide Function: The device uses a smooth gravity slide function within a two-part chamber system (shell and core) to naturally build smoke.

Compatibility: The Piston includes a removable 14mm male slide (bowl piece), making it compatible with other standard 14mm bowls. 

The Piston Gravity Bong measures 22cm x 9cm

The operation of the Piston Gravity Bong is based on the simple principles of fluid dynamics. 

First fill the larger outer chamber (shell) with water, ensuring there is enough space for the inner chamber (core) to be inserted without the mouthpiece being submerged.

Pack the Bowl: Lightly pack the included 14mm bowl with your chosen material.

While lighting the material, slowly and steadily lift the inner core upward out of the water. This action creates a vacuum, pulling air through the bowl and filling the core with dense smoke. Stop lifting just before the bottom of the core fully leaves the water line.

Remove the bowl from the joint, place your mouth over the mouthpiece opening and while inhaling, slowly and steadily push the core back down into the water-filled shell. The water pressure will force the accumulated smoke out of the chamber and into your lungs. 

We recommend taking it slow at first, as the hits can be very potent.
