Ronin 2 x 6.25 inch
Rated 5.00 out of 5$185.00Select optionsTHIS IS AN AIRGUN ONLY PART

This part is designed and manufactured by DonnyFL out of high-quality 6061 Aluminum.
The Ronin is made to quiet the big dogs. The Ronin is best on a high power .25 caliber or a Gauntlet .30 Caliber.
We only stock the .22/.25 , .25/.30 caliber, and .357 in 1/2 x 20 UNF threaded versions.
If you have a .22 caliber shrouded barrel PCP, you’ll want to order a .25 caliber suppressor.
The .22/.25 is for shrouded barrel .22 or direct barrel threaded PCP’s in .25.
The .25/.30 is for shrouded barrel .25 or direct barrel threaded PCP’s in .30. The exception to this rule is the Gauntlet .30 which is shrouded but because of the unique end cap, marries the barrel and shroud at the end.
The .357 is for shrouded barrel .30 calibers or direct barrel threaded .357 caliber PCPsIf you are looking to make the Ronin or Emperor really quiet, consider the 6.25″ Ronin extension chamber for extra stealthiness.

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

370cc/.37L CE 5/8″ Threaded
370cc/.37L/22.5ci Carbon Fiber 4500PSI Tank
$220.00Select optionsIntroducing a Hajimoto Productions Exclusive offer!
- Shaves almost a full pound of weight off your G2 or G30.
- 22.5ci/370cc/.37L CE Certified CF Tank.
- 5/8”-18UNF Threaded so Stock Gauntlet Regulators will thread directly to this bottle.
Installs on the Gauntlet 2 with minor tank shroud modifications, and the bottle shroud slides right over the carbon fiber cylinder.
The CF Tank is CE Certified and made to ISO 11119-3 standard. They have seamless aluminum alloy 6061 liner wound with high strength Japan-imported carbon fiber and glass fiber reinforced plastic full composite layers and subjected to an autofrettage pressure. This is a 22.5ci / 370cc carbon fiber 4500psi max fill cylinder.
The diameter of the tank is 54-55mm across so a modification to the forearm is required on a Gauntlet 1. I offer a tank shroud modification service for Gauntlet 1 owners that can be added to a build or provided as a mail-in service.
Please be careful if you have accessories on any of the M-Lok openings as the screws or MLok fasteners may protrude into the tank area and scratch the tank when the shroud is slid forward or back. We recommend that if you have any MLok accessories installed, you remove them when sliding the shroud on or off. We also recommend covering the brass inserts in the tank shroud with cloth tape to protect your carbon fiber finish.
