This full concave CNC spacer with tight manufacturing tolerences, gives improved shot to shot stability of the hopup spin.
Made from machined aircraft grade aluminium with a high-end anodize coating for ultimate stability and recognizable red Perfect Airsoft color.
Special engineered with soft radius edges to allow flathop compatibility without cutting into buckings! The perfect airsoft CNC Nub will give a wider and better grip around the BB, providing more spin with less effort and give an edge with heavy BB's in multiple scenarios like low-medium power setups or heavy pistons.
Also when cross-testing this against the original flathop nub, the vertical and horizontal spin consistency was slightly improved (which means everything for snipers).
Installation instructions: Simply unscrew the original hopup cover/arm, take the wheel out, change the nub and voila. Note that depending on your parts combination, it may need many rotations before the nub engages the BB! This is normal, as it was engineered for a wide compatibility.
