Description

MJ Arsenal Piston Gravity Bong

The Piston is MJ Arsenal's take on the gravity bong format, built entirely from handmade borosilicate glass. Where a standard gravity piece relies on a basic chamber and slide, this one adds a disc percolator inside the core, so the gravity-assisted draw passes through diffusion before it reaches you. The result is a gravity bong that filters more than it typically would, without adding complexity to the format.

The piston architecture is the defining physical feature here. The glass core sits inside the glass shell and moves like a piston, with a silicone gasket creating the seal between the two. That gasket is included and does the work that glass-on-glass alone can't do in this kind of moving assembly. The 14mm slide is removable and standard-sized, so it's replaceable through any supplier carrying MJ Arsenal parts or compatible 14mm accessories. At 8.75 inches tall with the bowl attached and 3.5 inches wide, it's a compact unit that doesn't take up much shelf or storage space.

This is a handmade piece, so expect the minor variation in finish that comes with that process. The disc perc inside the core is what sets this apart from MJ Arsenal's other gravity formats; it's not a feature found on their standard gravity bong lineup.

Good to know

  • The silicone gasket is the seal between the shell and core; keep it clean and seated properly for consistent draw performance.
  • The 14mm slide is a standard size, making it straightforward to replace if it breaks.
  • Handmade construction means small cosmetic variations between units are normal, not defects.
  • The disc perc is built into the glass core, not a separate removable insert, so cleaning the core is how you maintain the percolator.

Frequently Asked Questions

How does the piston mechanism actually work on this gravity bong?

The glass core slides up and down inside the glass shell, working just like a piston in a cylinder. A silicone gasket sits between the two pieces to create an airtight seal, so when you draw, the gravity-assisted pull moves smoke through the disc percolator built into the core for filtration before it reaches you. It's a simple motion once you get the feel for it, and the gasket does the heavy lifting to keep everything sealed during the draw.

How tall is the Piston Gravity Bong, and will it fit easily on a shelf or in a cabinet?

With the bowl attached, the Piston stands 8.75 inches tall and 3.5 inches wide, so it's a pretty compact piece that should fit comfortably on most shelves or inside a standard cabinet. Even with the core fully extended during use, the footprint stays small enough that storage is rarely an issue.

How does the gravity draw on the Piston compare to using a traditional bucket and bottle gravity setup?

The big difference is filtration. A classic bucket and bottle setup gives you a raw, unfiltered gravity hit, while the Piston runs that same gravity-assisted draw through a disc percolator built into the glass core, so the smoke gets diffused before you inhale. You also get a proper silicone-gasket seal between the shell and core instead of relying on water and a cut bottle, which keeps the draw consistent and airtight every time.

Can I replace just the 14mm slide if it breaks, or do I need to buy the whole set again?

Yes, you can replace just the slide on its own. It's a standard 14mm size, so any compatible 14mm slide from MJ Arsenal or other brands will work without needing to repurchase the full set. If you need help finding a replacement, feel free to reach out to our team and we'll point you in the right direction.

Can I use any standard 14mm bowl with the Piston, or does it only work with the included slide?

The Piston uses a standard 14mm connection, and the included slide is removable, so any compatible 14mm bowl should fit. That said, because of the piston's unique gravity mechanism, bowl depth or shape could affect how smoothly everything operates together. If you have a specific bowl in mind and want to double-check fit, feel free to reach out to our team and we'll help you sort it out.

How does the MJ Arsenal Piston compare to their standard gravity bong without the disc perc?

The big difference is the disc percolator built into the Piston's glass core. A standard MJ Arsenal gravity bong uses a basic chamber and slide setup, so the smoke goes straight from the bowl to you, while the Piston runs that gravity draw through disc percolation for added diffusion and filtration. Everything else stays familiar, including the handmade borosilicate glass construction and the same gravity-assisted pull mechanic, so the Piston is really an upgrade in smoothness without changing how you actually use it.

Does the glass core move smoothly inside the shell, or does it need to be broken in?

The silicone gasket between the core and shell is designed to create a smooth, airtight seal right out of the box, so there shouldn't be a break-in period. Just make sure the gasket is seated properly before your first use, and keep it clean over time so the core continues to glide consistently. If you run into any friction or fitment issues with your unit, reach out to our team and we'll get it sorted.

Is this gravity bong designed for dry herb only, or can it be used with concentrates?

The Piston comes with a standard 14mm glass slide designed for dry herb use. If you're looking to use it with concentrates, you could swap that slide for a compatible 14mm banger or concentrate attachment, though one isn't included in the box. Feel free to reach out to our team if you'd like help finding the right 14mm accessory for your setup.

How do I clean the disc percolator inside the glass core?

The disc perc is built right into the glass core, so you clean them together. Give the core a soak in isopropyl alcohol and coarse salt, then shake gently and rinse thoroughly with warm water to clear any residue from the perc's openings. Regular cleaning keeps airflow smooth and the diffusion working the way it should.

What does the disc percolator do, and how is it different from a gravity bong without one?

The disc percolator is built into the glass core, so as the piston draws smoke down through the gravity action, that smoke passes through the perc and gets diffused before you inhale. A standard gravity bong pulls smoke straight from the bowl into the chamber with no filtration step in between, which means you're getting a raw, unfiltered hit. The Piston adds that diffusion layer without changing how a gravity bong actually works, so you still get the full gravity draw, just smoother.
