Best CO2 Systems for Paintball: Tanks, Regulators & Parts

Curated from 339 real Reddit comments and discussions across 6 products.

Refreshed on: April 23, 2025

Snoop’s Take

In the wild world of DIY CO2 fueling, community champs share a few standout traits: rock-solid reliability, leakproof seals, lightweight aluminum builds, and enough shot capacity to keep your marker singing well past morn. Universal fit, fresh manufacture dates, and knurled adapters that won’t slip under pressure also win big Reddit karma. On the flip side, the worst offenders come with stuck lids, shredded O-rings, absent regulators, and that nagging sense that CO2 is so 90s—plus questionable value vs. paintball-specific HPA systems. Buyer beware: cheap adapters and throwaway tanks may leave you stranded mid-skirmish.

Top Considerations Before Purchasing

High Shot Capacity - Ensures longer play without refill panic.
Leakproof Design Matters - Prevent messy CO₂ leaks and performance hiccups.
Lightweight Build Wins - Reduces fatigue for quick maneuvers all game.
Check Regulator Needs - CO₂ tanks often missing regulators, add extra setups.
