The gun is only half the equation. Getting high-pressure air into the reservoir safely and affordably is the part new PCP owners most often figure out the hard way. Here's what the community runs.
Hill MK4 and FX pumps are the quality benchmarks. Works anywhere, no power required. 300 bar is a real workout — best for guns with smaller reservoirs or lower max pressure.
GX Pump CS4-I is the current community favorite for value. Yong Heng is the budget workhorse. Alkin and Bauer are the pro-grade options. All require maintenance and moisture management.
A filled SCBA cylinder and fill hose. Fast fills, no electricity, portable. You'll need a fill station or compressor to refill the tank itself — usually at a fire station or dive shop.
Lighter than steel SCBA tanks, hold more fills per pound. AirTanksPlus.com is the go-to source for PCP-specific CF buddy bottles in various capacities.
Oil changes, filter media replacement, moisture separators, and bleed valves — all of these matter more than compressor brand. A well-maintained cheap compressor outlasts a neglected expensive one. The forum has detailed maintenance threads for the GX Pump CS4 and Yong Heng specifically.
Water vapor in your fill line corrodes valves and reservoirs from the inside. A quality inline moisture filter and regular draining of your separator are non-negotiable. Ask the forum before your first fill — this is the lesson everyone learns once.
