Installation of our Sidelever on G2 or G1
This service is for the installation of our sidelever cocking system installed in your action. The Sidelever is no longer being offered for .30 caliber variants.
Our side lever system eliminates one of the main gripes folks have with the Umarex Gauntlet and that is COCKING EFFORT!
There is no comparison in cocking effort when you apply the mechanical advantage a sidelever gives you. The installation is a non-destructive installation and can be reversed without any compromise to the airgun’s action or stock.
The sidelever system is a CNC milled 6061 Aluminum part which is hard anodized for a great match to the existing Gauntlet finish. The cocking vertical handle is an additive manufactured carbon fiber & ABS part that can be swapped out by you if you wanted to use a custom handle from wood or other material.
Our sidelever cocking system does require that you hold the handle back to swap mags but there is no need to hold back if you single load using the single shot tray.
One of the most common questions we get is “Can I just buy the parts and install them myself?” and the short answer is, no you cannot. For the reasons why, please read the ARTICLE we published in our blog in February 2023 on this topic.
See below for detailed shipping instructions and preparation videos.
This service is to modify the bottle shroud to allow the proper fit for the Power Flex Combo carbon fiber tank and flex regulator:

The service can be added to an existing tune/build or a stand-alone ship in service. If you are shipping me your forestock or bottle shroud be sure to keep the screws, star washers, and sling stud as I will not need those. If you have any type of rail installed for a bipod it needs to be removed prior to shipping me the bottle shroud.
If you select the stand-alone ship service, shipping instructions will follow which detail the packaging and address to ship to.
