Ordering Information

Select the correct calibre, barrel length, and desired output in FT/LBS from the menu. For specific output pressure requests, please provide details. Note: For FAC models, output above 130/140bar is not recommended as it may reduce shot count and power.

Measuring Barrel Length

To measure, remove the shroud from your BSA R10. Measure from the barrel's muzzle to the front edge of the magazine port opening, then subtract 10mm. Common lengths are:

• Carbine: 300mm/12”
• Rifle: 380mm/15”
• FAC: 460mm/18”

If your barrel length differs by more than 20mm from any of these, please specify in the box indicated.

Installation Guide 

Refer to the PDF installation guide for detailed fitting instructions. The regulator arrives pre-set based on your rifle’s calibre, barrel length, and desired power output. Ensure you check the rifle’s output power post-installation to comply with legal limits.
