RA Hop-Up Spacer Set, A

Looking for maximum accuracy and a stable trajectory? The Retro Arms Set of Hop Up Spacers - Set A is a useful tuning set for the airsoft tech or shooter who wants the most from their hop-up chamber. These small spacers (also known as nubs) are the component that transfers pressure from your hop-up arm directly onto the hop-up bucking.

Optimised contact surface with different profiles

Set A from Retro Arms is designed to give you several setup options, so you can adjust the pressure precisely to your chosen hop-up bucking and the BB weight you shoot:

• Precision-moulded geometries: The set contains different spacer shapes that change how the bucking presses down into the barrel. This gives a more consistent, centred contact surface on the BB (backspin).
• Increased range and accuracy: Choosing the right spacer gives a more even, constant pressure. This minimises "flyers" (BBs veering off to the side) and can noticeably increase your effective range.
• Ideal with Retro Arms chambers: The spacer set is compatible with standard hop-up arms, but performs best in Retro Arms' own CNC-machined hop-up chambers.
