HUMA Regulator

[Pigeonator22]

Ey up Airgunners,

Iv recently got into the PCP side of things. Got a Gamo Coyote, and all I read is "stick a reg on it". So iv bought a HUMA one from HUMA themselves. Dont fancy putting it on myself, iv watched vids etc. Got in touch with a local gunsmith shop they said you'd have to mess with the anti tamper so theyre not willing to do it, which I think is not correct. Is thst a dude who wants to solely do servicing etc or am I likely to come up against this when trying to get someone to stick my reg on???

Not being funny but is there a specific reason for the reg ? Lots of guns don't have regs and are just as accurate as reg ones, only reason I can see to put one on is for increased shot count, your right with leaving it yourself because high pressure air is no joke, my daystate wolverine 2 isn't regged and it's near enough alpha wolf accurate, taking anti tampers off can void warranty, could try another gunsmith ?

I looked in to this for my Ultra TS which is essentially the same gun but it’s not as easy as it looks. The rifle was fantastic for accuracy just the low shot count made the sweet spot of the power curve to be slightly frustrating. For the money you’re investing you won’t see a great improvement and guns are a diminishing return anyway so maybe time to change to something else if you aren’t satisfied with how it’s performing.

Here’s the exploded diagram for reference anyway

Why the need for the reg? My old Coyote was fine without one, very reliable and accurate enough. Can't fault you if you really want to reg it but would like to hear your reasons.

Its not just a case of bunging a reg in

Alterations will need to be made in other areas, so they're right in the respect that they'll have to remove the AT as it will need a full stripdown to do the work

Cheers for the reply. Im fully aware of the fact its a full strip down.
My original question was not whether one would need to touch the anti tamper, but if im gonna struggle to get a gunsmith or qualified person to put it on(perhaps, as i said its a small job to them and not worth their time to bother with). Loads of places do upgrade work but wanna supply and install.

The reg is essentially to flatten the power curve mate. Its a pretty steep curve from my experience so far with the Coyote, and forums specific to these rifles the consensus is that a reg is the way to go. I am not a purist by any stretch and embracing the power curve aint what im after. Love a bit of nuance and quirkyness of course, but if there's something out there that, for me, makes my experience better, then I want it. Cheers for the comment pal

Ey up pal, cheers for the reply. Pretty much one reason. Iv noticed the "power curve" is quite pronounced. The reg is purely for consistency. Not bothered about shot count. Watched quite a few Coyotes and Urbans pre and post regulator and the consistency on the chrono is greatly increased.
And thats about it pal

@DM80 on here is a gunsmith and up your way

 

[Tricky-Dicky]

TBH the faffing about getting the setup right after fitting a reg will be the reason, as the firing valve and hammer/spring will need to be re balanced for the lower pressure, and the money you going to spend on someone doing that you may as well put it toward your next regged rifle, I suspect that is why the gunsmith didn't want to do it.

Bugger - responded to this but it looks like my post was lost

Bottom line it you need additional parts to support the reg installation (that for other rifles can be pilfered from other models, not so sure about the Coyote) as well as time and knowledge to correctly set it all up.

People exist with the ability to fit these regs, but tbh in paying someone to do a proper job you're going to be getting close to the value of the gun, and as such the money would most likely be more wisely put towards a better rifle.

The anti tamper is easy enough to remove with a flat blade screw driver its a roll pin. Heres the link to a simple YouTube video.

Im going down that same road I've got the huma reg, a larger transfer port and a lighter hammer spring from a lower powered version.

I have fitted a (literally) drop in Atros reg set to 100bar but the flb dropped to about 9 so I had to wind the preload up on the hammer spring a few turns to get to 11.5.

Shot count is abysmal 60/70 shots from a full 232 bar fill and drops off like a cliff 90 ish bar. Compared to well over 100. (In .22)

But my god is it consistent.

When I do the huma reg it will be set at 85bar with 4.5mm TP and a lighter hammer spring. Should see the shot count back around 90 or more and consistent from shot 1 to the last.

The rifle is fairly east to strip and rebuild you will need new seals. A strip down video I watched linked here.

I've watched and paused and rewound it loads of times and the exploded diagram above is very helpful.

Best of luck.

Honestly mate what a mint help that all is. The huma reg had a qr code link to a pdf with instructions for install, but they were a bit vague. One of the things they said was "open the transfer port up to 4-4.2mm". Can you just get a transfer port to that spec? Or will I need to physically open it up, drill it out or whatever? Im confident with the strip down and rebuild, not up there on refinery like lighter hammer springs etc. Could you give us a list of what you'd swap out/upgrade to compliment the huma install?

 

[Bradleyme]

Heres the link to the transfer port ill dig out the invoice for the spring with the part number

High Flow Transfer Port | Gamo / BSA Airguns | Ultra XL, Chacal, Coyote & More.. | eBay

Airguns are often sold (and adapted by the shooter) in a variety of ways. Making changes to the calibre, barrel length, pellet choice and many other attributes can alter the performance of your airgun.

I have a high power version knock off valve but have been advised I probably won't need it.

 

[Pigeonator22]

What a guy. Really appreciate it mate. Yes huma themselves say a FAC knock off valve is not necessary but something to think about moving forward. They call it an upgrade though, so not necessary doesnt always mean not better. Treating it as a bit of a project now, any info is invaluable and much appreciated cocker

Yeah no worries, keep in touch as you get along with it. I wont forget about the spring, I've just got back from pub

Ey up pal. You've forgotten about the spring havent you . Iv got the transfer port and im stickin a fac knock off valve on it regardless cos huma say its beneficial. So just spring needed and you referred to new seals. New in what way? Are they different, high power ones etc?
Hope im not interfering with your pub time again mukka

@Bradleyme
Why do you intend to install a Huma reg when you already have an Altaros?
You do know you can optimise the Altaros just the same? And you won't wreck the valve seat when you adjust the settings, as you are likely to do with the Huma.

I suspect your shot count is low because you don't have the Altaros set to the ideal operating pressure for your TP and plenum, so you are running at low air efficiency. In plug-in mode you should get as many shots as when un-regulated but the on-reg string will be flat. If you want higher shot count you'll need to do the other modifications (open up the TP and tinker with EV preload and hammer energy).

@Pigeonator22
i'd strongly advise against a 4-4.2mm TP. for sub-12. The absolute maximum you need is 3.5mm and, for peak air efficiency, probably less.

I've posted air efficiency curves and justified this in other threads. If you want more details or specific tuning advice you are both welcome to send me a PM.

Thanks for the offer Bill its greatly appreciated.

The Coyote is .22 and when it came to me I got 100 or more shots per fill and the power curve was obvious.

Started to drop off after 100bar.

The Altros reg was set to 100 bar and no other changes made.

The Altros reg values end at 100bar and the instructions say dont go past the end settings when making the adjustment.

Power went from 11.ish flbs to 9flbs and I had to add preload to the hammer spring which makes cocking it a chore and has turned it into a thirsty b*tch.

Your comment regarding the valve seat is the first I've come across while researching this particular rifle.

I wouldn't be surprised if there is already damage to it from the hammer slamming down because of the preload added.

There is more noise from the hammer action than from the buisness end and there's a hell of ping too.

Other advice and threads I've picked up on regarding reg pressures and TP sizes for. 22 are mainly from this forum.

My understanding is
85bar
3.5mm - 4mm TP
Softer hammer spring
May be a FAC knock off valve as per the Huma guide(?) I dont really understand the function of it. Is it longer or wider thus letting more air pass?

I got all the above off the sales forum.

My plan is/was
85bar on the reg
4mm tp
Soft hammer spring

I know of no companies that do lighter hammers or delrin guides for the spring. But where do you stop?

I could swap the TP and Spring out in and adjust the Altros reg down if its advisable against their instructions all in a couple of hours. The Huma reg fitting is a bit more work.

I could drill out the TP thats already in it. Sizes on fleabay are 2-5mm in 0.5 increments.

As for the knock off valve im too unsure.

Any way, I'm glad you chimed in. Given me something to think about.
