The BERSERKER Hop-up rubber made of polyurethanes, which was custom designed for the Delta Armory Hop-up chamber, is manufactured in Italy by the renowned manufacturer Psionic Upgrades. The rubber achieves the same effect as Maple Leaf's Macaron/Mr. Hop, but the big advantage of these rubber bands is that they will fit most popular Delta Armory/Lancer/Specna guns in a plug-and-play style - ie. The plug-and-play fitting can be used with the plug-and-play system without any additional modifications. Maple Leaf's Macaron or Mr. Hop elastic needs to be modified or the Hop-Up chamber needs to be padded to properly feed the gun.

We have tested the eraser for over half a year and are very pleased with it.

The price is surprising considering the package includes the rubber, 1x small OMEGA pressure roller, 1x large OMEGA pressure roller. The resulting price is even cheaper than the Taiwan parts from Maple Leaf/TNT/Prometheus or Modify. With EU made goods, we are mostly used to products being more expensive than those made in Asia.
