Install Super Tune Kit

Please note that these are services to your rifle and not just the parts. If your looking for parts only head to the PRODUCTS section of the website.

The service of installing the Super Tune Kit does not include shipping. Return shipping will be calculated and added at check out. Shipping cost will be based on a complete rifle sent to Hajimoto Productions in the original box and packing materials. Stock modification is part of the STK install which is why you need to send the entire rifle to us not just the action. If the rifle is received in something heavier than the typical 14lbs, additional shipping costs will need to be paid prior to the rifle being shipped back to the customer.

Super Tune Kit Users
You must use the stock trigger return spring with the two-stage trigger as the trigger spring that comes with the Super Tune Kit is too light to be effective with the two-stage trigger.

This can be added to a custom build order or a send-in modification request. Customers who wish to send in their barrel for service can ship either the entire rifle or just the barrel, barrel shroud, and end cap. The barrel will be heavily cleaned and coated with silicone oil to protect the surfaces for the trip home.

Once the order is received, a follow-up email will be provided. Depending on the service request, the response will contain detailed shipping instructions, including the shipping address and other pertinent information required on the label for the service request being shipped to us.
This service price does not include shipping or parts. Shipping costs to return your PCP or PCP parts will need to be calculated and communicated to you before the order ships back.

The reduction of an airgun barrel typically results in a decreased rate of travel of 15-20 ft/s per inch.

Any outstanding balance must be paid before we ship out the service order.

Remember to always order your suppressor one size larger for shrouded barrel PCP’s. DonnyFL Suppressors are sized so the first number is your PCP’s actual caliber and the second number is one size up. So if you owned a .22 caliber Gauntlet, the size you would select is .22/.25. If you had a .25 you would choose the .25/.30.

If Your Gauntlet is:
- .177 Get a .177/.22 Supressor
- .22 Get a .22/.25 Supressor
- .25 Get a .25/.30 Supressor

Installation of our Sidelever on G2 or G1
Gauntlet Sidelever Install
Original price was: $220.00.Current price is: $195.00.

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.
