Past perfect in hatsan bt65 sb ,monteren van de regulator was voor de eerste keer wel spannend omdat en geveild moest worden in de drukbuis en schroefdraad maar met de beschrijving op de site perfect gegaan.
Geen drukverlies en zeer constante schoten op 135 bar ingesteld.

Great product, easy to instal. Great customerservice. Tip: order the xl plenum. I have a Hatsan bt65, with xl plenum 275 ms at 140 bar (hammerspring adjusted to minimum tension).

Thank you huma Aires regulator is very very good

Giulio Azzali - 03-04-2018 16:13

Prodotto ottimo. Seguendo le istruzioni che ho trovato sul sito non ho avuto alcun problema a installarlo e trovare la regolazione ottimale per la mia BT65. l'ho tarato a 140 bar e, dopo avere lavorato anche sulla spinta della molla come indicato da Huma, riesco a tirare fino a 60 colpi senza notare variazioni di preciisione.
Apprezzazbile anche il supporto tecnico a cui avevo rivolto alcune domande prima di procedere all'installazione-
Veramente consigliato.

Na het monteren van de Huma regulator in de drukbuis van mijn Hatsan BT65 SB
afgesteld op 130 bar een merkbaar verschil in de geschoten groepjes.

Rafael Lomeli - 30-09-2017 07:16

Really great product. The regulator has increased my accuracy by so much. I'm getting one inch to one and a half inch groups at one hundred yards. I would really recommend this regulator as it's worth every penny.

Top Teil,man kann damit super einstellen. Tolles Prduckt.

Excellent regulator for taming my Hatsan BT65 SB Elite!
Good flat response ~1015-fps @ 130-bar using H&N Baracuda 10.65gr (I will be experimenting more with even lower pressures)
Lovely machining, easy to install and no modification to the original air pressure cylinder necessary.
Arrived in record time and really like the way the Huma team keeps the customer informed every step of the way and prompt response to all questions.

After a lot of research and reading reviews on the Huma regulator, I decided to purchase on for my BT65 and Galatian. So far it's been one the best decisions I have made as far as getting better performance from my rifles. Installation was quick and easy. Instructions were simple and easy to understand. Accuracy and shot count have improved dramatically. When I need another regulator for one of my air rifles, this will be my first stop.

Bought this regulator to tame my BT65SB, .177 cal from 35ft/lbs, 1250 fps to below supersonic and get the accuracy from 'shotgun style' to where it should be. Very high quality regulator, easy to install - I did use the second method of installation filing through the valve threads to allow regulator to vent. Ended up with the regulator set at 100 bar from 140 bar. Velocity down to 925 fps, muzzle energy around 22 ft/lbs and the consistency is incredible. Ping has also gone from the cylinder. Shot count up, air consumption greatly reduced. Using 10.65 grain pellets. Great product and Huma customer service is also very good.
Well done Huma Team, thank you.

Leslie - 03-01-2017 12:23

This is the second Huma I own , I have fitted the .25 regulator in a .22 for the bigger plenum volumn this is giving me 30 shots @ 40fpe with 21grn pellets. Very good product .

Al final no lo llegue a comprar.
Ya tenia uno, pero la verdad es que funciona bien.
La única pega es que por debajo de los 110-100 bares, no va tan fino.

Timothy Hutton - 08-12-2016 01:23

Got my regulator works great . got my feet pounds of engery I need in my bt65.25 cal at 75 yards for pellet speed. for kings 25.39 have not tried the 31.02 yet . I give the regulator 5 stars.

Luis M. - 04-06-2016 11:07

Well packaged. Easy installation, works perfect for the Hatsan BT65 airrifle, regulates perfectly the pellet speed, between higher speed and lower speed there is a diference of 2meters/second.
