The Hunt & Live take
Why this tank earns the pick
This is the tank you buy when the 3L Tuxing isn’t enough. 9 liters is 3× the capacity of the 3L — meaning if the 3L fills your PCP 30 times, the 9L fills it 90-100+ times before needing a refill. That’s a full hunting season or a year of competition practice on a single tank fill.
The integrated regulating valve means you don’t need a separate fill station — the valve handles pressure regulation between the tank and the rifle. For the off-grid PCP setup or the shooter who only wants to refill the tank once or twice a year, this is the right architecture.
What it pairs with
- Off-grid PCP setups — fill the tank once at a city shop or with your own compressor, then haul it to the cabin/homestead where you can’t easily refill
- Multi-rifle households — covers a Lynx Gen 3, an M60B, and an Avenger across multiple shooters without depleting between sessions
- Competition / club shooters — keeps a club’s PCPs filled across a full match weekend
- Any M18×1.5 PCP including the entire Snowpeak line, modern Avengers, JTS Airacuda, and current-gen platforms
Honest trade-offs
Size and weight are the headline issue. A 9-liter carbon cylinder is roughly the size of a small scuba tank. It’s a workshop or vehicle-trunk fixture, not a portable accessory. You’re not carrying this on a stalk. If you need portability, the 3L or 6.8L are the right choices.
No fill station bundled in the title listing — the regulating valve is on the cylinder itself, but you may still want a fill station for the connection to your rifle. Verify what’s included before ordering, or pair this with the adjustable regulated fill station for the complete setup.
Refilling logistics are the same as the 3L. This is a CE-certified tank (not DOT) — scuba shops in Canada won’t fill it. You need your own PCP compressor (Tuxing, Yong Heng, or equivalent), or you arrange DOT re-inspection. For an off-grid setup, this is fine; for a city buyer who wants scuba-shop fills, look at the Scott SCBA cylinders instead.
