Replace the factory AMP regulator in your FX Dreamline (pressure tube version) with the Huma-Air Tuning Regulator and get rid of the pellet-speed fluctuations and pressure creep that plague the stock unit. CNC-machined from aircraft-grade aluminum with bronze internals, this regulator has proven itself in USA Extreme Benchrest competition.

It drops into the pressure tube in about a minute as a direct replacement for the original regulator, adding extra regulated air volume along the way — meaning more consistent shot strings, higher achievable power, or the same power at a lower, more efficient regulator setting.

Key features:

• Stepless adjustable output pressure: 70–155 bar (covers both sub-12 ft/lbs and F.A.C./high-power setups)
• Clear pressure scale label for easy fine-tuning or re-adjustment
• Shipped preset to your requested pressure, or the most common setting
• Includes a "Huma-Air Regulated" breech sticker and fitting instructions
• 2-year warranty (excludes normal wear items like O-rings and valve discs)

Fits: FX Dreamline with pressure tube, serial numbers up to approximately 2121769 (FX changed the internal regulator design around mid-2021 — later serial numbers need the Bottle Version regulator instead; let us know if you need help identifying yours)

Note: this is the standard Tuning Regulator. A higher-volume 30cc Power Plenum XL version is also available for maximum power and extreme tuning — ask if you'd like that variant listed instead.
