Description
The AIRTECH Retro Arms Rotary True Centering Unit is an internal component for Retro Arms hop-up chambers. It is the rotary part of the assembly that presses on the hop rubber, and the true centering layout applies that force down the middle of the barrel rather than from one side.
Because it is made specifically for Retro Arms chambers, it is aimed at players who already use that chamber and want to replace the rotary piece or set up the hop side of a build. Check your chamber model before ordering, as this is a dedicated fitment rather than a universal part. Installation involves opening up the hop-up assembly, so it suits someone happy working on the barrel group and gearbox. Keep your original parts to hand when swapping it over.
