HUMA REGULATORS VS. FX REGULATORS FOR WILDCAT & STREAMLINE

Chuck,

What a pain this has turned into. So I perfectly aligned the grub adjustment screw on the new FX AMP Regulator. Not once but 3 times. I even put a Allen wrench in the grub screw to hold it in place. When the cylinder is pressurized it slides back. I think the spacer is to small. As johan from FX stated "If you remove the stock you will see that there is an identical hole on the other side of the tube, but in this hole there is a Regulator adjuster screw. ​In order to adjust it you will need to line up the screw with the hole, however for functionality you will not need to line it up". So the regulator is functional, as long as it is between the 2 o-rings; however, forget about adjusting it externally. Check your .30 compact. There is a little rubber plug by the cylinder mount. Pull that our and see if there is a grub screw visible. If there is you are in business. Be careful where you place that grommet. It is round and the size of a 12 gauge buck shot. Easy to lose track of and will bounce like a little ball if it hits the ground. Really bad design. Also, I can only get 150 Bar in my rifle. Not sure what that is about. I may have to pull that plastic derlin washer after all. I tried with a metal pick but to no avail. And, when I was tightening down the Wika gauge the platsic cover popped off and the old piece of s--t Fx gauge broke when I was pulling it. Not real robust. Is crying OK if your an airhead? Friend of mine just called and reminded me we were going hunting tomorrow. Explained the situation; and, now he thinks I'm crazy. Why'd you tear that dam thing apart. He might have a point there.

Are there any photos of this new regulator? Nick, silly question but could it be in backwards? It's happened before. It would be super cool too that it could be retrofitted in the older models. You don't realize how sweet externally adjustable regulators are until you use one then have to go back and tweak one that's all internal.

Oh yeah, I can relate to the ease of destructibility the FX gauge is. Been there done that too.

Chuck,

Finally had to walk away from it last night. Got up before the birds were singing, 0400 (Da), Figured out how to get that plastic washer out. Put a screw in there and pulled it out. Found a o-ring that fit and tightened down the Wika. It isn't quite centered. However, I like it like that as I don't have lean over the barrel to read it. Anyway, figured out why I could only get 140 Bar. Well I used my 18 cu/ft air tank to fill my cylinder back up from empty. The light bulb finally came on and I realized there is only so much sand you can put in a 5 Lb bag. Used my air compressor and brought her up to 250 Bar. Nice thing about this stubbed toe...learned that the Wika gauge is balls on accurate. No leaks and pressure is holding just fine. 

Not sure why the AMP will not stay lined up. Pretty difficult to put that thing in backwards. You would have to pull the fill port and push it out if it were in backwards. As a matter of fact, I never did see the adjustment grub when I pulled that little fricken rubber ball they use to cover the vent hole. So something is wrong in Norway. (Or, should I say Sweden). Johan wrote me from FX. He actually answered my previous questions somewhat more satisfactorily. I do believe FX may be monitoring this forum. Any how the following was my response:

Johan,

My problem is the vent hole does not line up with the adjustment grub. I think the spacer is to small and therefore the adjustment screw slides back under pressure. What size spacer should be in there? The AMP Regulator sounds great. However, what good is it if you can't access the adjustment grub (screw)? It certainly appears more robust than the old regulators. I would love to play with it. I understand it is operational; but, it is not installed as intended. As a consequence, it is not operating as intended or advertised. Therefore, it is not functional. You must know that Huma will develop a regulator targeted at your product. This would indicate to Air-gunners that your regulator is sub par. I'm not saying it is. Never the less, prospective customers may turn to other manufactures that are now utilizing Huma Regulators in their air rifles. I am pleased that I have the AMP Regulator in my rifle. Again, like I have tried to make clear I am not happy that I can not utilize it to its full potential. Thank you for advising me of you your regulator setting. That is the kind of information that should be made known. Also, using that little round plug to cover the vent port is not very well thought out. If it hits the ground, good luck trying to recover it. Your air rifles are a very popular brand. And, there is a vast community that discuss your products. I am certain the new AMP Regulator will be very much scrutinized as it well should be. Please advise how I can line my adjustment screw with the vent port.

Sincerely,

Nick 

On well, at least I know that FX sets their regulator at 140 Bar.

Later,

Nick


 
Chuck,

If line the adjustment screw on the side that is under the stock, I assume that is what you are saying, than I would have to pull the stock to adjust the regulator. If I'm reading you correctly. When I first inspected my rifle, I noticed this little rubber grommet (ball). Pulled the grommet and all I saw was solid silver. It was for that reason I contacted FX and asked why there was a machined hole drilled into my cylinder. I did not know there was a 2nd hole covered by the stock as well. My understanding of the vent port was a small pin sized hole near the top of the cylinder. I thought it was a mistake. Now mind you, there was never any cap screws showing at this time. Nothing advised me of a upgraded regulator and how it functions. After pulled the air cylinder and accessed the regulator did I realize this was not the regulator I anticipated finding. I had read some where that FX was implementing a new regulator and sure enough I had one. I almost feel like taking the Huma spacer and drop it down in there to see if it makes a difference. I wish I would have taken my micrometer and measured it. I was going to go out and see how it fires this morning. Not sure I want to tear it apart again. At this point, as FX said, it is functional. Not as intended albeit operational. How do you introduce new technology and not advise the customer of same? Cripes sake we're talking about weapons here....

I agree, get the slug liners out to us please. Had I bought a Brocock Sniper or Commander, I'd most likely been pounding pigeons with slugs at long range from day 1.

About the gauges, I don't understand the complaining about them being cheap. First guys complain about the price tag of FX rifles, but when FX uses (presumably) a less expensive gauge to keep the price reasonable (presumably), guys complain about that. 

I fully understand the question as to why not just use the Huma regulator to begin with (like Brocock did) as it seems there are never problems with those. This hobby is a huge money pit either way one goes about it.

I personally have not had a problem with the factory reg in my Streamline or Crown, nor with the gauges. The Wildcat, yes the factory reg went bad and the Huma got put in. But the gauge with that I was fine too.
 
You are correct Bob it is an expensive hobby. Should never have messed with that gauge. On the other hand, its winter, in the upstate Sc, so good time to learn this rifle. Military training instilled knowing your weapon and keeping it clean. This is your rifle this is your gun, grabbing crotch, this is for fighting this is for fun. Guns in the military are artillery pieces. Use the wrong term and it was good for 100 push-ups. Thats why I always use the term rifle when describing my weapon. This Wildcat is much more complex than the M-16 or M-14 rifles. In one of your posts, you mentioned you would not mess around with your Wildcat unless it began having issues. (Something to that nature.) Again, absolutely correct. Some of us, however, just have to take things apart. Oh well, you play you pay. Guess I'll blame it on Uncle Sam....
