MJA Piston Gravity Bong

The MJ Arsenal Piston Gravity Bong puts a modern spin on a classic gravity setup with a bold, mechanical-inspired design and smooth, controlled performance. Handmade from premium borosilicate glass, this piece features a unique piston-style build paired with a first-of-its-kind disc percolation system that cools and filters each pull for a noticeably smoother experience. Instead of relying on bulky setups, the Piston uses a gravity slide function to create dense, efficient pulls with minimal effort. Simply lift and lower the glass core to generate airflow, allowing gravity to do the work while maintaining consistency from hit to hit. The removable 14mm slide makes it easy to customize your setup or clean between sessions.
