MJ Arsenal Piston Glass Gravity Bong

Meet the MJ Arsenal “Piston” — a compact glass gravity bong that turns every session into a smooth, satisfying pull with a clever piston-style core.

Built from 100% borosilicate glass, the Piston pairs a wide, stable base with a first-of-its-kind disc percolator to add diffusion without overcomplicating the setup.

Why You’ll Love It
The piston action makes it easy to build a dense hit and clear it cleanly, while the disc perc helps mellow the draw for comfortable, flavor-forward rips. It’s a great pick when you want “big bong energy” in a small, countertop-friendly footprint.

Care & Usage Tips

• Rinse with warm water after sessions to keep the perc holes flowing freely.
• For deeper cleaning, try Formula 420 Glass Cleaner (great when you want an alternative to isopropyl).
• Handle the gasket gently during disassembly so the seal stays snug.

Intended for legal use by adults 21+. Keep out of reach of children.
