The PDI W-Hold (50 Degree) hop rubbers are soft and tight with external ribs to push against the hop chamber.
They fit snugly on virtually all barrels to create an excellent seal.
The softer Nitrile material performs superbly at low temperatures and remains grippy enough to float medium/heavy weight ammo.

The internal mount is split to allow the BBs to be kept perfectly centrally to create a much more consistent and even backspin.
The lips are an excellent shape and work with the vast majority of hop chambers. This is our go-to hop rubber for any build with an awkward hop chamber (eg. TM MP5s or VFC SCARs) and any build where the target ammo weight is equal to or lower than 0.32g.

Please apply a drop of liquid silicone oil to the external surface prior to installation. This helps the hop rubber and barrel slide into the hop chamber evenly.
Check the hop rubber is evenly spaced and the split in the mount is central prior to rebuilding the RIF.

Around 3mm will need to be trimmed off the end (including the lower rib) when this hop rubber is installed into a NGRS hop chamber and at least 5mm when paired with a TM/Cyma M14 chamber.

The lips on this hop rubber are a little wider than many others so this rubber works in systems where others would bind. Some level of hop must be applied to retain the BB in the chamber.

We recommend pairing this hop rubber with a flat nub for best results.

Our custom flat nubs are now available on the shop :)
