Loose Cocking Handle?

by Hajimoto

G1 or G2 Loose Bolt Handle quick fix

Watch this quick video and tell me if you have the same issue.

Have no fear, below is the step-by-step procedure to correct this very simple issue.

The issue is the 2.4mm tipped grub screw (set screw) fits into the detent hole in the bolt handle and is just not tightened enough resulting in a very safe mechanical interface but because the pin is in the hole of the handle, the handle rotates easily on that pin. The procedure will impart more tension on the set screw forcing the shoulder of the tipped set screw to bite into the bolt handle causing it to stop wiggling around.

The Corrective Procedure:

  1. The rifle's bolt should be forward and the safety off.
  2. Be sure the airgun is unloaded and uncocked by aiming in a safe direction and pulling the trigger.
  3. Remove the retainer screw(s) for the foregrip and remove.
  4. Remove the left and right stock to action retention screws.
  5. Remove the long Phillips head screw in the bottom of the stock that holds the action into the stock.
  6. Aim the safety lever down to allow it to clear through the trigger guard slot in the stock.
  7. Push the action up and out of the stock; taking care to keep track of the black filler plug.
  8. Loosen the rear trigger screw (Phillips head).
  9. Slide it out only enough for the upper button cap to be removed.
  10. With the button cap removed look inside the upper cavity and you will see a hex screw.
  11. First loosen and then tighten the 2.5mm hex screw that is in the rear of the pellet probe which grips the bolt handle.
  12. Reassemble the airgun.

Thats it! Now go have fun shooting your G1 or G2!

Gauntlet Barrel Twist Rate

by Hajimoto

There has been some conflicting information that has been published regarding the Umarex Gauntlet and its barrel twist rate.

Please let me end all the misinformation that is out there once and for all. Whether we are talking about a Gauntlet 1 or a Gauntlet 2 either in .22 or .25 caliber, all Gauntlets have a right-hand twist of 1:20" and the barrels are choked. The exception is the Gauntlet 30 Caliber which has a 1:18 twist rate.

I have been told that the Umarex USA has told folks 1:24" and another G2 owner told me that they read or heard that the twist rate was 1:15". I am not arguing the truth if it was said or not, I am simply eradicating incorrect information.

Again to be clear, all G1 and G2's, have a right-hand 1:20" twist rate. The exception is the Gauntlet 30 Caliber which has a 1:18 twist rate.

Carbon Fiber Your Gauntlet 1 or 2

by Hajimoto

4500PSI Carbon Fiber bottle with installed Ninja Pro V2 Regulator

Now offering pure straight-up sexy for your Umarex Gauntlet. Whether you have a Gauntlet 1 or a Gauntlet 2 you can add this combination for reliable fixed operating pressure regulation that means more shots and more power, if that is how you request it to be built. HERE

Straight-up sexy!

The Ninja Pro V2 regulator is world renown for consistency and reliability with low standard deviation and velocity spread. We will build the regulator to output whatever pressure you want from 1100PSI to 2400PSI so you achieve not only the look you want but the power you desire.

This combo is a direct replacement for the stock tank and regulator without any modifications. The Gauntlet 1 will need to have its foregrip/tank shroud covers inside diameter increased because the carbon fiber tank is just slightly larger.

This is a custom cerakoted Hajimoto Edition Gauntlet 1 with the CF tank installed.

We have and still offer a tank shroud modification service if you choose to have us do it for you. Here is what the tank looks like on a Gauntlet 1.

Remember to please follow recommended maximum operating pressure guidelines to prevent your Gauntlet from being damaged or worse, someone getting hurt.

Xisico Compressors Finally In

by Hajimoto

Hajimoto Productions finally received the Xisico personal high-pressure compressor order. This is a small lightweight AC/DC compressor that will fill your PCP in minutes. The unit uses synthetic oil (included) and is air-cooled. It can run off your vehicle's battery terminals or use the AC to DC converter.

The unit has an auto shut off feature where you set the desired pressure and when the compressor reaches the set point the pump stops but the cooling fans keep going so the unit has a properly cool-down period. This compressor is designed for the filling of your PCP directly and not intended to fill larger bottles used for in the field recharging. Because it is air cooled, there no buckets of water or grease issues to be concerned with.

I personally abused one of these units for over one year and it was used every single day to fill at least one 13ci bottle every day and that unit is still being used today without issue. Because I build custom regulators the test chamber needs to be filled multiple times per build and this unit was tasked with that job and it never once failed me. It kept me from starting up the large compressor or depleting my large bottles.

The unit comes with everything you need in one box which allows you to be independent and fill your PCP's whenever you want. For the cost of a large carbon fiber tank which you need to hydro test and pay to have filled, this allows you to fill where ever and whenever you want.

Let me know if you have any questions,
