Boro Mod Beginner Guide - Billets, Bridges and RBAs Explained | 2FDeal
Boro mods -- also called billet-style devices -- have taken the vaping world by storm over the past few years. If you've seen these compact rectangular devices and wondered what the hype is all about, you're in the right place. This beginner's guide covers everything from what a boro mod is, to choosing your first bridge or RBA, to where to find the best boro accessories.
What is a Boro Mod?
A boro (short for "borosilicate") mod is a box-shaped device that houses a proprietary "boro tank" inside the body rather than having an atomizer sitting on top. The concept was popularized by the Billet Box, but today there are dozens of compatible devices and accessories.

Choosing Your First Bridge / RBA
This is where boro mods get really interesting. The bridge determines your vaping experience -- MTL, RDL, or DL -- and whether you use prebuilt coils or rebuild your own.
For MTL Vapers
- Dotshell V2 Style RBA: Comes with 5 air pins for fine-tuning. A great starter RBA for boro newbies.
- YFTK Monarchy Mobb TC Style RBA: 7 air pins, wide adjustment range. Excellent flavor.
For DL / Restricted DL Vapers
- MK Mods Infinity RBA: Premium bridge with 8 air pins. Known for smooth airflow and dense vapor.
For Drop-in Coils
- Capsule Style Adapter: Converts your boro tank to use Uwell Caliburn G / G2 pods -- the convenience of pod coils in a boro mod.
Essential Boro Accessories
Once you have a mod and bridge, you'll want to stock up on:
| Accessory | Why You Need It |
|---|---|
| Replacement Glass Tubes | Spare tanks in case of breakage |
| PCTG / PEI Tanks | Plastic options -- unbreakable for travel |
| 510 / 810 Drip Tips | Customize your draw and comfort |
| Drip Tip Adapters | Use 510 tips on 810 boro bridges |
| Coiling Tools | Screwdrivers, cutters, tweezers for building |
Boro Mod Checklist for Beginners
- Choose your mod -- pick a DNA60/60C device that fits your style
- Pick a bridge/RBA -- start with a 5-8 air pin RBA for flexibility
- Get spare tanks -- order 1-2 extra tank tubes (glass + PCTG)
- Stock coils and wicks -- grab prebuilt DIY coils and cotton pads
- Choose drip tips -- experiment with different bore sizes
- Pick batteries -- use authentic 18650 batteries
Common Boro Questions
Q: Are boro mods only for MTL?
A: No. Many bridges support RDL and even DL vaping. Check air pin options -- 8+ pin bridges like the MK Mods Infinity cover MTL through restricted DL.
Q: Can I use my existing atomizer on a boro mod?
A: No -- boro mods require a boro tank and bridge system. Your standard RTA/RDA won't fit.
Q: Is a boro mod harder to build than a regular RTA?
A: Slightly. The build deck is smaller, so you'll need good eyes and steady hands. Start with a spacious RBA like the Dotshell V2.
Q: How often do I need to replace the o-rings?
A: Every 3-6 months depending on juice use. Order spares when you buy your first bridge.
Final Thoughts
Boro mods represent the most customizable segment of vaping today. The combination of pocket-friendly size, chipset versatility (especially Evolv DNA), and an almost endless variety of bridges and accessories makes them deeply satisfying for tinkerers and flavor chasers alike.
Start with a solid DNA60C mod, pick a bridge with plenty of air pin options, and don't forget the spare tanks. Welcome to the boro rabbit hole -- it's deep, but the view is fantastic.
