Remember it is recommended that you order your suppressor one size larger for shrouded barrel PCP’s.
If you have a .22 caliber shrouded barrel PCP, you’ll want to order a .25 caliber suppressor.
The .177/.22 is for shrouded barrel .177 or direct barrel threaded PCP’s in .22.
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 Tanto, Tatsu, FX, or Sumo are not recommended for the Gauntlet .30 caliber because of the relatively small internal volume of these suppressors and the elevated operating pressures of the G30. We recommend the Ronin be used on all of our G30 Builds.

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.

5/8″-18UNF thread can be used on 3000PSI bottle as well. This regulator is built with the ball/pin and spring removed so hot swapping will not be able to happen.

We do include the ball/pin and spring should you happen to have a thin pin depression system capable of actually opening the valve.

You should never try and unscrew a high-pressure output paintball-style regulator (anything over 1000psi output) while it is under pressure. You will destroy the threads as they are not designed to be threaded on and off under load. Degas and then remove the regulator and bottle.

Tighten the degassed tank and regulator assembly fully to the rifle, then back it off until the fill port is on the bottom and the gauges are left and right. Now fill the bottle with air and all will tighten up solid. Proper alignment will be achieved before the 360° maximum rotation limit is realized.

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.

FX Pocket Chronograph v2

The original FX Chronograph changed airguns by providing the
most important tool a modern shooter must have, in a compact, portable unit. Now FX Airguns is pleased to introduce the even smaller and improved FX Pocket Chronograph v2.

The v2 Pocket Chronograph is more pocket sized than ever at just
under the size of a 2” cube. It now has an internal battery that is recharged through an included USB-C cord. Multiple mounts are also included that allow the shooter to attach the chronograph to their rifle in multiple ways.

The chronograph itself can be used for more than just airguns. Any
projectile traveling under 1250 FPS can be accurately measured. This includes subsonic rifles, pistols, CO2 air rifles, paintball, and more. Since the unit uses radar technology, the Pocket Chronograph can be used in any weather condition without external accessories.

The setup is the same as the older version. To learn how to use it, follow the link here to watch the tutorial video.
