The MJ Arsenal Piston Gravity Bong elevates a smoking tradition with mechanical-inspired design and high-performance engineering. Featuring a first-of-its-kind disc percolation system, this piece solves the "harsh hit" problem common in traditional gravity bongs. Handmade from premium borosilicate glass, the Piston uses a smooth gravity slide function to deliver filtered, powerful hits with every cycle.
Standing nearly 9 inches tall with the included 14mm slide, this piece is a modern take on the DIY classic. Its piston-shaped core and sleek glass shell are designed for enthusiasts who appreciate technical precision. Because of the added percolation, this piece reward a steady, patient draw technique—a small trade-off for the smoothest gravity-fed experience on the market.
