The Notos is, by far, the most popular airgun we make parts for. Many folks in the airgun community asked for a Notos Pump Action and we obliged. Please note, you will need the side lever for the pump action to work. In order to make this pump action work smoothly we had to change out the OEM sidelever for a conventional side lever handle. The pump handle is connected to the new side lever with a link arm and is retained by a stainless steel knurled dowel pin. The pump action was the goal, but we also ended up with a more ergonomic side lever, so were offering that for sale individually as well. These parts are compatible with the OEM stocks for the Umarex Notos and Artemis/Snowpeak PP750 and with our AR grip adapters for those models.
