High flow, V2, dual hole transfer port with middle support bridge for FX Impact, FX Dreamline,  FX Wildcat MKIII and FX Crown.

 

The successor to our high flow dual hole transferport;  we have managed to optimize and even enlarge the air passage in this new version 2 of our High Flow V2 Dual Hole Transferport. The V-shaped transfer opening makes sure you will have the maximum and smoothest air passage area. The middle support bridge divides the transfer port into a dual hole port. This middle bridge makes sure the pellet or slug nose cannot fall into the enlarged transferport hole, but will be guided smoothly by the middle bridge into the barrel.

This dual hole transfer port has much larger air passage area compared to the oem port for maximum perfomance.  The increasement varies by caliber:

In combination with our High Flow Slug- and Pellet Probe you will be able to get even more power out of you Fx Impact

 

Caliber  Surface Enlargement
.177 285 %
.22 176 %
.25 117 %
.30 122 %







 

Please note:

Any modification done to the airflow of your rifle, will affect the entire setup and performance, you might need to re-adjust the settings of your rifle again to get the best posible performance.
Due the already huge increase of the airflow opening, the .177 dual hole model is not V-shaped


We have modified the o-ring groove dimensions and and locating notch of the transferport to be compatible with both the newest rifles as well as the older versions from FX.
Before tightening the grubscrew that holds the barrel in the breech, make sure the barrel is adjusted properly so the magazine slides in and out smoothly.

Another great product from Huma-Air, ordered and received in USA with no issues. Installed and tested seen immediate gains in FPS

Brian Furth - 24-02-2021 20:27

Fantastic product and fantastic service, more than happy to deal again.

Thanks

Graeme - 18-02-2021 23:05

Excellent product and I have fitted these to a few FX rifles. I always get excellent results once fitted and have never had a problem with one.

Vanheusden Sven - 09-02-2021 15:01

I bought the Fx dual transfer.
Within a few hours it was shipped out.
Two days later it did arrived.
I mounted it the same day.
Works perfectly.
It sure is an update.
Thanks Huma-Air

All products I’ve had from huma have been excellently engineers tu the finest tolerances do not hesitate tu buy at huma

Dai jones - 18-01-2021 14:10

Great upgrade to the FX range of guns, great quality and huma have a great team behind them.

Simon - 04-01-2021 18:43

Zowel dual port als pelletprobe daarvan kloppen de maten niet met originele montage. Heb upgrade op mijn nieuwe dreamline .25 gemonteerd. Het magazijn past niet meer. Tip: dualport niet helemaal laten aansluiten en pin van de pelletprobe afvijlen totdat magazijn weer past. Snelheid wel verbeterd.

dennis crowell - 29-12-2020 01:49

I don't think I received the V2. This looks just like the one on my .25 Crown. The walls are straight up instead of angled like I thought the would be.

Naif Fattah - 27-12-2020 09:43

Awesome kit, easy installation and a great improvement to my gun.

I only wish that Huma ship their products with DHL.

Samuel GLL - 25-12-2020 00:51

Quite nice step forward in fps. Very useful if you work with slugs and the pin probe ;)

Dale D-RIG - 18-12-2020 04:31

The V2 transfer port in .177 cal is awesome I installed this on a 600mm barrel
and using the .177 pin probe this 177 cal Impact really came alive , lots of power .

peter - 11-12-2020 14:22

Every possible improvement in speed is good ,but you can not go above the max accuracy of the gun with a certain slug or pellet ,but the better way is to lower the plenum pressure ,you will have more shots per fill and less stress at the internal of the gun and keeping the speed .

SPYRIDON - 09-12-2020 21:47

Brilliant!!! Very easy to replace the factory one. Combined with the pin probe boosted my impact mk2 by 40-50 fps with knockouts and HN 25 gr without touching anything else.

Chris Kennaman - 08-12-2020 07:54

High quality product, easy to install especially if you watch the video's and with the usual Great HUMA Service

RMB - 07-12-2020 10:27

Snel en goed geleverd..top

Ray - 04-12-2020 09:37

I've had huge increase in speed using this in .22 .30 and .35 cal next will be the .25 and I'm expecting over 100ft/sec increase coupled with the new pin pellet probe it's bolt-on power....

Dai jones - 30-11-2020 10:41

Great item and quality, also great service fro huma.👍

Thomas van Eil - 23-11-2020 16:24

Really good product.

I only gained about 8 fps on my crown with the standard pellet Probe. But in my opinion way more important: it made my speed a lot more consistent. If you want max accuracy or a little more power, this is a small investment with big results!

Be careful when changing it, the original can be pretty well glued on, make sure to heat it up enough.

Bandido - 18-11-2020 15:39

Excellent delivery, on time and well packaged
The product fulfils my expectations both in terms of quality and performance

Richard - 15-11-2020 21:35

Brilliant & well made.

Willem Plantinga - 11-11-2020 14:34

In combinatie met de nieuwe pellet probe is dit een perfecte combi om meer fps te krijgen om zodoende zwaardere pellets en ook slugs te verschieten. Nog beter is het om dan ook de hamerveer erbij te bestellen. Geeft veel meer ruimte om je Dreamline af te stellen
Dank je wel Huma.

Edd - 07-11-2020 10:42

You guys out there want a power upgrade for your impact Go for this little gem amazed I was well worth the money

Oliveira - 31-10-2020 14:22

Produto Excelente!!

Edd - 25-10-2020 17:56

I couldn't believe it MK1 impact 25cal took it from 808fps to 867fps just by putting the high flow V2 dual transfer port on . Well worth the money

Ian tunstall - 25-10-2020 09:52


I bought the transfer port from huma to try and fix the problem I was having as soon as I fixed it the problem disappeared extremely pleased with it thank you very much

k. Gurung - 12-10-2020 21:33

Huma high flow tp looks so nice that had arrived a week ago & have not used yet and i am sure this will do better performance as its reviews.

Ben Ballard - 12-10-2020 00:41

Instant power increase. Watch some vids all the way through so you don’t miss anything. Precision made piece, exact fit, I picked up 45+ FPS with just this upgrade. Couple less with the Nielsen adjustable probe and the consistency is jaw dropping. I would highly recommend all huma air products to any one looking to tune their gun for high performance high efficiency. Thank you huma for being so reliable.

Jani - 29-09-2020 13:23

Quality of product is fantastic. I have installed on my Dream Pup .22cal bottle . With my settings I don't see big difference between original and this dual hole port. My settings beafore instalation was 115 bar (AMP) reg. preasure with small (original FX) 17cc power plenum - reasults: 18gr JSB ... around 895 fts (SDEV is 4,097 fts) and 44 constant shots from 230 to 115 bar. After instalation my JSB flaying 900 fts, all other is same. Measurmens was done with AirChrony MK3. My big deal wast still done with PowerPlenum. I need to try with slug and higher settings of regulator, liner, ... and other toys for air rifle boys.

Francisco - 21-09-2020 11:36

I haven't tested it yet ... but I hope it speeds up, as it is referenced

Andrew - 19-09-2020 23:29

Brill company very happy

Steve mcneil - 19-09-2020 22:45

increased the power to suit slugs in my wildcat

Tom - 19-09-2020 05:08

Easy to install. Works as advertised.

Diego Rezende - 13-09-2020 16:52

I’d to thank Huna-Air for a very to quality product that I’ve bought from them very good customer service fast delivery 🚚 📦
Well done guy surely I’ll buy some more stuff from you guys .
Many thanks ..

Please continue with this great service.

Regards !!

Diego Rezende.

Tom - 13-09-2020 06:51

It uses air more efficiently. If you are mechanically inclined at all, it is a very easy installation.

Gkharv - 09-09-2020 01:44

“HUMA’s” Transfer Port and Pellet Probe” is“Ground Zero “ for starting upgrade on your Impact. In 22cal my rifle gained 47fps without making any adjustments. This translate to better air efficiency. Simple - fast - easy to install. This 2 piece assembly should be a part that needs to be an install part at factory.

Mr R Lovering - 08-09-2020 18:16

Excelent Product and service

Josenicolas Garcia - 26-08-2020 00:41

Excellent, it give me 75 FPS more and it works excellent !

Ricardo Silva - 19-06-2020 22:25

Excellent product and quality, only huma air needs to produce the pellet probe for dreamline to keep the opening equal to the transfer port dual hole, PS .. for a perfect fit between the transfer door and the magazine, first install the barrel , according to insert the magazine, third tighten the screws that fix the barrel, I hope I helped.

Osmo Hyvärinen - 16-06-2020 09:59

with the dual hole transfer port and high flow pellet probe, you can gain about 40 - 50 fps..
it is not so much than DIY shaped probe with dual hole transfer port.. (those gained about 80 - 90fps)... but, HUMA probe pushes the pellets and slugs better than "half moon" shaped probe and if you enlarge original parts yourself, you might break something.. so "plug and play" HUMA parts are easy to install and you also save the original parts!

Wyan - 14-06-2020 17:56

No more pellets/slugs stuck in transfer port

Mauro Brogio - 10-06-2020 21:28

Hi,
excellent product, requires a bit of manual skills, but the result is guaranteed. I measured a speed increase of 15 m / s compared to the original transfer port.
A cordial greeting from Italy

Oliver.L - 07-06-2020 20:27

have installed on .22 and .25 with significant fps gains. in .25 can easily get 36.2grain slugs up to 970fps at @140 bar using my Impact with the Power Plenun. extremely happy and the installation is not a difficult undertaking.

Johan S - 03-06-2020 18:52

Huma deliver as always!!
Quality and easy to install, fast delivery to sweden in a few days its hanging in a bag on my door.
Very pleased!!

Tony - 02-06-2020 13:52

great item cant wait for the .177 version to become available

Malcolm - 01-06-2020 17:33

works very well going to order another in .22 and one in .25 very efficient.

Johny Morton - 01-06-2020 13:52

Very High quality product that helps unleash the full potential of my fx crown combined with the gen 3 regulator I’ve also fitted fantastic company to deal with as always

Antonio - 29-05-2020 08:14

Great product as all of your products

David Stevenson - 28-05-2020 00:52

I bought and installed the .22 cal dual transfer port from Huma. The part was pollished and precisely made. Installation was fairly easy. I installed it on an FX Dreamline and tested it a few days later with multiple pellets and slugs. I received a significant increase in fps when I adjusted my front power setting to .25/.30. I see no downside to incorporating this design into my guns. I highly recommend the product.

Hyung - 25-05-2020 03:26

bought 3 right when the pandemic started in america and shipment got canceled. Huma contacted me about the problem and provided alternative delivery method and refunded my money. Order 3 again and huma shipped out asap and got even faster. Awesome service thank you again.

3 high flow for: FX impact mk2, dreamline tact, dreamline tact compact

Leon - 24-05-2020 22:39

👌

Vicente m - 22-05-2020 21:32

Works great. I gained 15 FPS out of my .22 cal crown by only adding this custom transfer port. I lowered the hummer spring tension and reg pressure and got my same velocity with more shots per fill. Thank you Huma air.

Lucien Thibo - 21-05-2020 15:31

Initially the impact fx has a power of 41 joules. In combination with the power plenum, resort voltage on 3 and regulator on 120 bars, test carried out with jsb pellets 1.03 ranges the power of the rifle is 50 joules.
One word is perfect

Crusher - 19-05-2020 14:39

I can't say enough good things about these regulators. In every application so far, I have gotten a much smaller ES and steady performance. A smaller ES relates to a better consistent shot string. Which in turn brings you to more consistent shot placement. If you haven't tried this HUMA reg, get one now. You will be glad you did.

Tony - 18-05-2020 10:39

.25 Details - the original Round port is 5.1mm Diamter (area = 20mm) and the Huma dual is 6X7.2 (area 43mm) minus a little for the bridge and for the round corners

I reckon the Huma is at least 40mm area which makes it double the size of the original

I can now get the same pellet speeds with Minus 20 Bar in my Regulator, which is at least 1 magazines worth.

Many thanks Huma - cant wait for the 177 Version to arrive.

Anthony Conti - 16-05-2020 14:24

Great power mod! Installed this and a hammer spring weight to pick up 80 FPS.

Kurt - 14-05-2020 18:06

Excellent service as always, top product and increase by at least 30FPS

Osmo Hyvärinen - 13-05-2020 06:59

An excellent accessory if you want to take all the power out of your FX. With this and modifielded pellet probe you can get about + 50fps.
I sanded and chamfered some sharp edges off and got 2-4 fps more.. I think it's not worth it because you might destroy a ports.

Tony - 12-05-2020 11:58

Awesome item, it has had the effect of allowing me to reduce the Reg Pressure to 25bar and I am still getting 12FPE, I shudder to think of how many shots I will get in .22 on 500cc bottle now!

on mine the location slot had been made a bit too long so when I first fitted it the magazine wouldnt fit, so I backed the barrel out and inserted the magazine and the then reinserted the barrel - this worked fine. (Crown)

Many thanks Huma - will order another one soon

Woody Terminator - 08-05-2020 09:50

I got a small section of 0.5 brass sheet from eBay to copy Ernies Rows tutorial - also used it to snug up the new one from Huma - shame there isn't a .177 version - guys can you knock me up a .177 version please?

Ben M - 28-04-2020 22:26

Great product if you are looking to get the most power from your rifle. It definitely works great and would recommend this for those using slugs as your primary ammo

Gerald Wooding - 28-04-2020 21:48

Very well machined and superbly finished. Fitted with no issues following one of the many YouTube videos. Gained 20 FPS at 135 bar on my .25 Crown. Very pleased.

Paul de Jong - 22-04-2020 11:41

Top product.

Paul - 20-04-2020 01:15

Perfect as is everything i buy from huma..

Carlos Rocha - 08-04-2020 07:18

I’m very happy with the excellent quality the two holes transfer port is made. I’ve already installed it together with the power plenum kit and now my fx Impact is working just perfect when shooting slugs.

Rick Calcott - 02-04-2020 23:47

Fantastic replacement to my standard .22 version. Machining quality, fit and finish is superb and consistency is improved through a better, smoother airflow. You need to apply gentle heat to take the factory item off because of the loctite, but nothing aggressive and I left the breech o ring in place through the process. Very smooth pellet loading into the breech also because of the support piece - we’ll do e Huma.

Muhammad Usama - 01-04-2020 03:39

Excellent product.

Muhammad Usama - 01-04-2020 03:37

Excellent product. Gave an extra 30 fps above the Orignal transfer Port.

Rick Calcott - 31-03-2020 17:02

This modification works really well in my .22 Dreamliner classic. Pellet loading in to the breech is very smooth, and in conjunction with my Huma-Air regulator shit to shift consistency is excellent. Works well for me and very happy with the purchase, which was very quick to deliver and easy to instal. Just needs some gentle heat to take the original off the barrel and loctite the new one in place. No need to take the breach o ring off, just the two outside barrel seals. Tick in the box for Huma.

Tom - 28-03-2020 19:17

Brilliant upgrade to original and huge power gains especially in .22

Mika - 27-03-2020 19:39

Good product, but pellet probe is going to need some modification also.

Hannu Leino - 26-03-2020 08:46

Very well machined part

Ben Mcardle - 25-03-2020 11:57

Works great I ordered 2 of these 1 in .22 and 1 in .25 got them installed fit great and load butter smoth I be ordering a .30 cal one next very pleased my dreamline is up to 49.5 foot pounds of energy now in .22 shoting 26gn slugs very pleased great job Huma

peter - 25-03-2020 08:53

,allereerst (dit gaat over de dreamline , voor de impact heeft krale youtube filmpje) de O ringen voor verhitten op en in de oude transferpoort verwijderen,
1draai de demper of kartel moer van de loop af
2 draai de inbus schroefjes los 2 stuks
3trek de loop eruit en trek de mantel naar voren na deze los gedraaid te hebben op de liner .
4 verhit de oude brass/messing transferpoort en draai deze los montage , nou je kan de oude ook best met tang pakken ,want ik denk niet dat die ooit weer monteert wordt of gebruikt en wil je die oude redden gebruik dan pen in het poort gat als hevel
5 maak de nieuwe HUMA dual flow port vetvrij en de loop reinigen van de loctite resten en breng nieuwe loctite (Groene)aan op de loopschroefdraad draai de huma dual poort erop , stevig handvast is genoeg maak de O ring groeven schoon ,beste is nu om de loctite een paar uur te laten verharden of wat op de verpakking staat. en bij montage van de loop o ring monteren op overgang loop transferpoort , wat silicon vet op de o ringen ,
schuif loop in receiver en draai een beetje zodat een pen in receiver in groefje transferpoort valt .plaats eerst leeg magazijn en draai imbusjes dan pas vast niet overdrijven.rest weer monteren
ps
tip en dan is het tuning tijd , met de dual flow wil je ook de plexum ,want met een fx plexum en of in combinatie met de huma reg en plexum kan de druk in plexum ruimte omlaag want je wil niet harder met pellets dan 285 m/s wegens schot precisie of daarom heen .lagere druk in plexum is ook goed voor de kleppen zittingen. buffers en dichtingen,wegens lagere stress.

Ben Mcardle - 18-03-2020 23:30

Works great I got the .22 and .25 and will be ordering the .30 soon. Definitely increased performance in .22 I haven't tried the .25 yet but everything fits beautifully and loading was very smooth. These are currently on my fx dreamline with plenum and getting around 50 fpe in .22 with my reg under 145bar still so very pleased. Great job Huma!
