MJ Arsenal Spire Bong: Sleek Design, Elevated Filtration
Some bongs look great but feel a little rough around the edges in daily use—awkward splash, inconsistent diffusion, or a pull that just isn’t as refined as it should be. The MJ Arsenal Spire Bong is built to solve those little annoyances while still keeping the silhouette clean and display-worthy.
Designed by Andy Roth, the Spire leans into a modern, architectural shape that feels intentional: stable base, comfortable height, and a filtration setup that prioritizes smoothness without turning the piece into a cleaning nightmare. If you want a bong that feels “premium” every time you pick it up, the Spire is exactly that kind of upgrade.

Troubleshooting Tips

Feels harsh: Increase water a touch until percolation is more active (small changes go a long way).

Weak diffusion: Add a small amount of water until you see consistent bubbling through the perc.

Helpful Answers
What makes the MJ Arsenal Spire Bong feel smoother?
The MJ Arsenal Spire bong uses a second percolator to add extra filtration, which helps cool and soften the draw. That extra diffusion can make pulls feel more refined—especially if you like a smooth inhale without losing airflow. The built-in splash guard also helps keep things comfortable, so you get the clean feel you want without messy water travel.
Summary: The MJ Arsenal bong feels smoother thanks to double filtration and a splash guard that keeps pulls clean.
What joint size is the Spire bong?
The Spire features a 14mm joint and includes a 14mm flower bowl in the box. That means it’s ready to use immediately, and 14mm is a common size that many people prefer for a snug, stable setup. If you already run a 14mm routine, the Spire fits right in.
Summary: The Spire bong uses a 14mm joint and ships with a matching 14mm bowl.
How much water should I add to the MJ Arsenal Spire?
Start low and add water slowly until you see consistent percolation without splash. With a splash guard and double filtration, you don’t need to overfill—too much water can restrict airflow or create splash. The sweet spot is when bubbling is active and the pull feels smooth, but water stays controlled.
Summary: The best Spire bong performance comes from a carefully dialed water level—enough to perc, not enough to splash.
Is the Spire easy to keep clean?
Yes—its borosilicate construction makes rinsing simple, and a consistent routine (emptying after use and rinsing) keeps buildup manageable. A deeper clean as needed helps preserve that clean airflow and taste. If you want accessory ideas that complement a bowl setup, our grinder guide is a great next read.
Summary: The MJ Arsenal Spire bong stays fresh with simple rinsing and occasional deeper cleaning.
