Gauntlet 2’s being offered

by Hajimoto

Waz Goin Owen Peeple??

Well, ladies and gents, we have Gauntlet 2's in the house and ready to be offered to you all!

I will be building the Copper, Silver, Gold, Platinum, and Ultimate packages on a first come first serve basis. Order will be processed in the order they were received. As I always do, if my deliverable time pushes out to 14 days, I will pause receiving any additional orders until I get caught up.

It is important to note, that I have published a heads up as well as a banner on the top of the site that I will be at RMAC from 8/25 to 8/31 so orders that land in that time frame will not be processed until September 1, 2021.

I anticipate a fairly large surge for these Gauntlet 2's but I will do my best to get your build out before I leave for RMAC in nine (9) days. Typical build times are 10 days but again, I will do my best.

So again, I will do all that I can to get the first few out before I leave but plan on any order placed from 8/18/2021 on, to be built when I return.

Thank you for your support and I look forward to building your G2!

Portable HPA compressors moving fast.

by Hajimoto

Hey guys and gals. Just a heads up that its Christmas season and the high pressure portable compressors are moving fast. I only have a few left and am waiting for the next shipment to arrive. The issue is that the demand was so high that the shipment has been delayed and I fear I will run out before December 14th which is when I was supposed to receive the additional skid.

What I would hate to see happen is that folks wanting to have their compressor for Christmas, may miss the opportunity afforded by in this inventory wave.

Airgun Expo 2021!

by Hajimoto

As you all know there will not be a Shot Show in Vegas this year but worry not because in January of 2021 there will be the largest virtual airgun expo ever created. There will be airgun industry leaders that will have demonstrations and unveiling of the hottest equipment known to man.

There will be live video streams of demonstrations, product reviews, product features, pricing and release dates. There will be special coupon codes that will be issued that only the Airgun Expo will be privy to which means, so will you!

Keep an eye here for any changes as they happen so you do not miss out on this amazing industry first. The Event is being created by Gateway to Airguns and will be in Texas.

Gauntlet Transfer Port Talk

by Hajimoto

The purpose of porting, polishing, chamfering and bird mouthing air conveyance infrastructure is to reduce drag or pressure drop and inducing velocity stack. More efficient airflow to the projectile, in turn, increases projectile velocity.

Because velocity is increased, less hammer preload is required because the internals are delivering the air more efficiently which in turn, increases shot count.
The key and most important thing to remember is that the transfer port outlet inside the barrel should never exceed 80% of the bore diameter. This only because when loading a pellet into the breech anything larger than 80% tends to grab the projectile and gouge or deform it.

The projectile will try and load into the transfer port if the transfer port is too large.

The key is to taper and smooth like a funnel towards the chamber. Bird mouth the inlet side of the transfer port in the barrel so it is larger than the outlet side of the barrel again funneling the air rather than fighting a sharp 90° transfer of direction and creating jetties or vertices that essentially reduce the flow by upwards of 50% (See attached sketch).

Just like in engine building, anything you can do to help an aspirating system loose drag or pressure drop is an improvement in performance.

Umarex is making changes and for the better!

by Hajimoto

As most of you know I am a huge fan of the entry-level PCP known as the Umarex Gauntlet which comes in .177, .22 and .25 calibers. I have been pretty vocal to Umarex regarding the issues that Gauntlet has which could be addressed relatively easily and not really incur any additional machining/fabrication time to correct. The issue is that there are thousands of these parts that are already rolling off the line and an introduction into an already rolling production line will cause a huge ripple effect in delivering the product on time.

So as with most manufacturers, the product will go through generational upgrades and changes over time. Well, some of the comments that folks have made are finding their way to the generational evolution of the Gauntlet. Some of the main issues with the Gauntlet were:
Weak Barrel Support
Cracked Air Strippers
Difficulty Cocking

The poor barrel stiffness issue caused huge point of impact changes with only slight physical contact with the barrel shroud was made. The POI issue was solved by the community with things like barrel bands, woodblocks and other ingenious ways to support the barrel shroud. I offered a barrel band which introduced additional support from the bottle to the barrel shroud, Well Umarex picked up on this issue and quickly designed an integrated barrel shroud support system that attached to the bottle block. This barrel shroud support that is being included on the then new .25 Caliber, was promised to previous Gauntlet owners as a part that would eventually be available. It was also said that this new improvement would be included on any fractional generation .177/.22 caliber Gauntlets produced.

The Umarex Gauntlet barrel shroud support on the .25 worked really well and folks were banging Umrarex's doors down to be able to add this to their .177/.22 Gauntlets. The addition of the support required some drilling and mechanical fastening which could be installed improperly and cause additional issues that the manufacturer was not ready to accept. So after a few 30 or parts were sold the support line was lit up with calls of installer error or difficulty installing the part. Umarex quickly stopped offering the part and offered the support as a service that they would perform and send the rifle back to the shooter. As you can imagine this additional shipping back and forth made the shipping companies a lot of money and also put the airgun owner in a position where they were without their beloved Gauntlet for a week or more plus the shipping cost.

Well as I stated earlier, the factory is retrofitting existing stock with the upgrades like
Barrel Shroud Support.
Beefer Air Stripper.
Better fitting o-ring on Air Stripper.
Stronger screws at the bottle block.

I know this because, in one of my recent airgun orders of 12 rifles, all the .22 caliber versions were upgraded. Take a look at the photos here and you will see that they are hard at work to improve the Gauntlet for the end-user and this is awesome to see. The images I provided are of a .22 caliber and show the improvements that were made to an existing stock rifle, the reason I know this is that the star washer imprints in the pressure tube are clearly visible. I also have erased the last digits of the serial number as this will be in the hands of a customer at some point and I do not what their serial number used by some unscrupulous characters that may exist out there ?
I will continue to report changes as I discover them and will try my best to field any questions you may have.
Be Safe!

GREEN LIGHT!

by Hajimoto

Hello my air gun friends!
Today I am announcing that the Hajimoto Productions moratorium has been lifted! I have worked very hard to get all the tunes, builds and custom orders out the door. I have also replenished all the parts and add-on that where wiped out from the hunting season rush.

As I have explained before and just to be clear, I do not entertain backorders. It has been my practice to open or close sales acceptance based on workload. If I have so much work that delivery times exceed my 15-day maximum turnaround time, I hit the pause button. My logic is, if I am having a hard time managing the current flow, why start a line of waiting customers that can wait upwards to weeks just to be in another line to get their orders processed. I operate by the first come, first served rule.

I would like to thank you all for your patience during these times of RED LIGHT.

SOLD OUT!

by Hajimoto

Hey guys! As you know over the past 1.5 months or so I have been hit hard by tuning requests and sales of tuned Gauntlets. As I posted a week or so ago, I place a moratorium on taking any additional orders until I got caught up. Well since that time, almost every mod I produce has been sold out.

So I apologize if almost every item you try to place in you rcart pops up as "SOLD OUT" but I am working diligently working to get those inventories back on line and open the gates once more.

I will be restocked and ready to receive orders for airguns, tunes and parts on Monday 10/12/2019. I will make another post to the news once I have things ready to go.

Thank you for your support and understanding,

2019 Hunting Season Rush

by Hajimoto

As most of you know I was hit with a substantial amount of Hajimoto Tunes and Gun Requests for the 2019 Hunting Season. Because I do not offer backorders, I adjust accepting additional orders so I do not exceed my self imposed maximum turn around time of 14 days. Typically my workload allows me to receive, build or tune a rifle and ship to the customer within 10 days or less.

I forecast that I will start accepting orders again within 7-10 days. That means somewhere around October 14th 2019 or so I will be accepting orders for tunes, builds and purchases of Hajimoto Tuned rifles. I will be posting this change here on the home page of the site so it will be easy to see the green light that I am receiving orders once again.

Please keep in mind that the Christmas season is fast approaching and this is typically another very busy time for me so we will be seeing this surge effect again soon. So if you are thinking of having services or purchases as a gift, act early.

Thank you for your continued support and understanding,

Hajimoto Productions.

Moratorium lifted!

by Hajimoto

I am caught up and appreciate your patience as I filled the huge wave of tunes and sales that splashed in. As I have done in the past, I will continue to execute this method in the future. Rather than take back orders and have folks in line for months, I will simply pause accepting any additional orders until I get caught up. That said, Starting today June 3, 2019.

I will be accepting rifles for tuning and orders for fully tuned Gauntlets. The Hajimoto Edition Gauntlet is now available as well!
