Frequently Asked Questions
Do X Custom bundles work with my HPA tank and platform?
Yes. Our bundles and the XELTA Regulator² are designed as plug-and-play for common HPA setups across CQB to DMR. XELTA works with low-pressure and high-pressure tanks and is adjustable from 10–250 PSI. Each bundle is curated so you don’t have to chase missing parts.
What makes the XELTA Regulator² different from typical regs?
XELTA uses a dual-piston design: one piston isolates bottle pressure, the other holds your set output rock-steady—so performance feels consistent whether the bottle is full or nearly empty. It also includes cold-weather details (anti-frost considerations) and an easy-to-read, tinted gauge window.
Is the X-Hose³ compatible with US QD/Foster and winter conditions?
Absolutely. X-Hose³ is a premium microbore braided remote line with US-standard QD and stainless fittings. Our Cold-Ready seals keep their elasticity in low temperatures. The default bundle length is 110 cm, with up to 14 colorways available.
How fast can I get playing, and what’s in the box?
It’s truly out-of-the-box: connect the bottle → set PSI → verify on chrono → play.
- Premium 3-in-1³: XELTA + X-Hose³ (110 cm US QD) + X-Tank 0.8 L / 3000 PSI
- Premium 4-in-1³: everything above + T-Flow Pump² (4-stage hand pump for fast top-ups anywhere)
How many shots from the X-Tank 0.8 L (3000 PSI)?
In typical CQB-style settings around ~100 PSI, users can see up to ~5,000 shots per fill. Real-world count varies with barrel length, dwell, PSI, and play style—consider it guidance, not a guarantee.
