Aftermarket PCP Regulators

A PCP regulator is the small but critical component that drops the high reservoir pressure (250-300 bar) to a fixed firing pressure every shot. On an unregulated PCP, the firing pressure equals whatever’s in the reservoir at the moment — meaning your first shot off a fresh fill is at full reservoir pressure, your last shot is at the low end, and only the middle of the fill gives you consistent velocity.

An aftermarket regulator turns that 60-shot fill into 50-60 shots of identical velocity — your first shot reads the same on a chronograph as your fortieth. That’s the difference between a hunting rifle and a target rifle, and it’s the most impactful single-component upgrade most PCP owners make after their first season.

The hard part is that every regulator is rifle-specific. There is no universal PCP regulator — each one is engineered to drop into a specific rifle’s reservoir end-cap and pressure path. The 10 regulators we feature below are grouped by rifle platform; find your rifle, then pick the maker.

When upgrading

What to look for in a PCP regulator.

  • ✓
    Regulators are rifle-specific — there's no universal model Every PCP regulator is engineered to drop into a specific rifle's reservoir and pressure path. You can't buy a 'generic' PCP regulator — Altaros makes a Stormrider/Bandit regulator, a PP700SA regulator, a PP750/M11 regulator, and a Beeman Chief II regulator, and they're all different parts that won't interchange. Verify the rifle model exactly before ordering.
  • ✓
    Altaros vs Huma vs Lane — what's the difference? Altaros is the gold-standard Czech regulator maker — premium internals, precise output, the upgrade of choice across most modern PCPs. Huma-Air is the Dutch competitor — very similar quality, slightly different design philosophy, popular for FX and Artemis platforms. Lane is the budget alternative — good performance for the price but not the same shot-to-shot consistency as Altaros or Huma.
  • ✓
    Why upgrade to a regulator at all? An unregulated PCP delivers air directly from the reservoir to the firing valve. As reservoir pressure drops, shot velocity rises (over-velocity from a fresh fill) then falls (under-velocity at the bottom of the fill). You get a narrow 'sweet spot' of consistent velocity in the middle of the fill — maybe 20-30 shots out of 60. A regulator drops the firing pressure to a fixed set point regardless of reservoir pressure, giving you consistent velocity across the whole usable fill — 50-60 shots of identical performance instead of 20-30.
  • ✓
    Verify your reservoir's max pressure before setting the regulator Aftermarket regulators are adjustable to your rifle's max safe pressure. The Snowpeak M60B is rated to 300 bar, the Lynx Gen 3 to 250 bar, the Avenger to 250 bar — these are the maximums you can set the regulator to, not the maximum you should. Set the regulator 15-20 bar below the rifle's stamped max to give yourself safety margin for temperature swings.
  • ✓
    Most regulators require basic tool work to install Drop-in regulators replace the rifle's existing pressure transfer port assembly. This means partial disassembly of the reservoir end of the rifle, swap in the new regulator, reseal with the included O-rings, and reassemble. Plan on 30-60 minutes per install if it's your first time. Most installations don't void warranty if done correctly; some do — verify before opening the rifle.

Every regulator below is a drop-in replacement for a specific rifle. Find your rifle in the list, pick from the available regulator makers, and buy direct from our partner.

Diana / Artemis · StormRider / Bandit / PR900W / PP800

The most-supported regulator family in the partner's catalog — 3 different regulator options for these platforms across Altaros, Huma, and Lane.

Diana / Artemis · PP700SA / PP750 / M11

Different reservoir architecture from the StormRider/Bandit — needs the PP700SA-specific or PP750/M11-specific regulator.

Diana / Artemis · Fill valve + gauge assembly

Not a regulator per se, but a complete fill valve and gauge assembly upgrade for the Diana/Artemis platforms — replaces the original valve with a more reliable unit.

Snowpeak · M60 / M60B / Umarex Zelos

The Snowpeak M60-family regulator drop-in. Same regulator covers the M60, M60B, and the rebadged Umarex Zelos. Fits the [M60B High Power](/pcp/rifles/snowpeak-m60b-high-power/) and the [Umarex Zelos](/pcp/rifles/umarex-zelos/).

Beeman · Chief II / Chief 2 Plus / Raider

Altaros-made regulator specifically engineered for the Beeman Chief II family. The upgrade for any Beeman PCP buyer who's serious about shot-to-shot consistency. Fits the [Beeman Chief II](/pcp/rifles/beeman-chief-ii/) and [Beeman Raider](/pcp/rifles/beeman-raider/).

JTS · Airacuda (all variants)

JTS's Airacuda family is the modern Picatinny-chassis platform — this Altaros drop-in is the regulator upgrade. Fits the [JTS Airacuda Max](/pcp/rifles/jts-airacuda-max/), [Airacuda PRS Max](/pcp/rifles/jts-airacuda-prs-max/), and [Airacuda Standard](/pcp/rifles/jts-airacuda-standard/).
