The PDI W-Hold (70 Degree) hop rubbers are strong and tight with external ribs to push against the hop chamber.
They fit snugly on virtually all barrels to create an excellent seal.
The harder Nitrile material performs great in low temperatures and offers superior stiffness at higher pressure levels. This helps improve power consistency and is ideal for pairing with R-Hop installations (modification required).
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 where the target ammo weight is between 0.28 - 0.30g and power consistency is key, or where heavier ammo will be used when paired with an R-Hop.
