Buy the MJ Arsenal Ursa Mini Dab Rig if…

You want a compact glass dab rig that can properly filter your vapor without becoming too large to use comfortably. The Ursa is a great fit if you like quick, flavorful hits from a compact 10mm setup. It also makes sense if you care about day-to-day cleanliness, since the built-in reclaim catcher helps keep more mess out of the water, and the rear downstem layout keeps the rig feeling stable and predictable once the water level is dialed in.

How It Works

The Ursa Mini Rig follows the standard quick routine most glass rig users are accustomed to.

Here’s how you can use the MJ Arsenal Ursa Mini Dab Rig:

• Fill the rig with water through the mouthpiece until it slightly covers the base-connected discus percolator.
• Insert the included quartz bucket into the 10mm joint.
• Use a torch to heat the bottom and sides of the quartz bucket evenly for about 20–30 seconds.
• Add your concentrate into the banger while gently inhaling through the mouthpiece.
• Place the carb cap on top and continue inhaling(heat slightly if necessary)

Pro Tips: Start with less water than you think. Add a little at a time until the perc is active and the pull feels smooth. Mini rigs respond better to slower, steadier pulls than sharp inhales. That is usually what keeps the filtration cycling properly.

Swab the banger after each session while it is still warm. It keeps flavor cleaner and makes the rig easier to maintain.

Vapor Quality

The Ursa is a mini rig, so the challenge is always the same: you want real filtration, but you do not have the space for long chambers and big recycling loops. MJ Arsenal’s solution is the incycler layout. It works like a recycler, but the drain and return paths are built inside the body instead of sitting outside as big tubes. That internal routing is the whole point; it gives you a recycling style pull in a compact footprint.

The discus perc is the second piece that makes the vapor feel smooth. It is a fast diffuser, so cooling happens quickly, and the hit feels smoother without needing much space. And the reclaim catcher matters here as well. Its main purpose is to keep the main water chamber from getting dirty as fast. When the water is clean, your session stays flavorful.

Last but not least, the Ursa Mini Rig has a rear-mounted downstem, which helps keep water splashing to a minimum. It does so by allowing vapor to travel through the water, without reaching the mouthpiece.

Manufacturing Quality

The Ursa Mini is a compact borosilicate glass rig, and the build is clearly focused on packing a lot of functionality into a small footprint. That matters here because the incycler layout is not just a “shape choice.” It's a complex internal structure, and it needs solid execution to work consistently over time without feeling fragile.

The way MJ Arsenal handled that is by keeping the whole system tight and integrated. In a mini rig, that is a big deal for day-to-day handling, because it keeps the piece slimmer and easier to move around without it feeling awkward or wide.

The joint and downstem layout also fits the use case. It is a 10mm mini setup, so you naturally want to be mindful of side pressure on the banger, but the rear-mounted downstem, and the percolator keep the rig feeling stable when it is sitting on a desk. It is a small piece, but it does not feel top heavy once the water level is set correctly.

Cleaning and Maintenance

Keeping the MJ Arsenal Ursa Mini Dab Rig clean is essential to ensure maximum performance and flavor quality.

Here’s how you can clean the MJ Arsenal Ursa Mini Dab Rig:

• Remove the quartz bucket and carb cap from the rig.
• Empty any remaining water from the rig, then rinse it with warm water to loosen any remaining residue.
• For deeper cleaning, pour isopropyl alcohol (91% or higher) into the rig, adding coarse salt if needed for extra scrubbing power.
• Cover the openings and gently shake the rig to help break down buildup inside the percolator and internal chamber.
• Let the rig sit for a few minutes, then rinse thoroughly with warm water.
• Allow the rig to air dry completely before using it again.

Pro Tips: Always let the rig cool before cleaning to avoid thermal shock. For best results, clean lightly and regularly rather than waiting for heavy buildup, especially with incycler rigs, where residue can collect in hard-to-reach areas.

Compatibility with Various Accessories

For loading concentrates, tools like the Utillian Hot Wax Axe make the process much cleaner and more controlled. Instead of dealing with sticky residue on traditional dab tools, concentrates can drop directly into the quartz bucket, reducing waste.

Maintenance is just as important for a rig with an internal incycler system. Using a dedicated cleaning solution like the Zeus Purify Cleaning Kit helps keep both the glass body and quartz bucket free from buildup. This directly supports better airflow, smoother draws, and more consistent flavor over time.

The Ursa Mini also works seamlessly with common upgrades like carb caps and terp pearls, which help regulate airflow and improve heat distribution inside the bucket. Its compatibility with alternative quartz bangers and simple adapters also gives you room to experiment with different styles without changing your entire setup.
