Gravity bongs just got a serious upgrade. The MJ Arsenal Piston Gravity Bong reimagines a classic format with premium borosilicate glass construction and a first-of-its-kind disc percolation system that filters and smooths every hit before it reaches you. The result is the power you expect from a gravity bong with a level of smoothness you absolutely don't.

The mechanical-inspired piston design looks as impressive as it functions. The glass core slides inside the shell with precision, building chamber pressure that drives dense, flavorful smoke through the disc perc on every pull. The removable 14mm slide keeps things easy to load and clean, and the silicone gasket ensures a tight, reliable seal every session. Handmade from 100% borosilicate glass at 8.5 inches tall, it's built to be a centerpiece of any setup.

For anyone who thought they already knew what a gravity bong could do, the Piston is about to change that.
