    Why put a gauge on the plenum?

    On the FX guns made the last years, there is no other way to adjust the regs, than to do it on the gun itself. So it is not just an convenience, but also a nessesity.

    Why put a gauge on the plenum?

    From an tuning perspective, the reg does not need to read the exact presise pressure. If it read 10 bar to much or to low is not that important. The most important is that it does not fluctuate, fooling the owner thinking the reg is faulthy. And that it is possible to read the difference in at...

    Why put a gauge on the plenum?

    It makes the most sence on external adjustable guns, where you do not need to take the gun apart to adjust the reg. Guns which require to be taken apart, may void waranty if the customers do it. And thouse who do, will mostl likely use a regtester anyway. Hard to read the pressure when the gun...

    FX Fps all over the place fx maverick

    If you reg is not opening, or are slow, I would try lower the regpressure . For 16 grain pellets you do not need 100 bar or more. Since the Maverick has a very big plenum, the reg can in some cases "stick", if you use to high pressure compared what is needed. If you tune the gun following some...

    Taipan .177 backyard friendly Tiapan set up

    I do own a taipan, and even I have not focused trying it on low power, I think the gun is quiest consistent (on speed) by just turning down the hammer spring force. It doeas not need to be tuned at the "knee", meaning you can have relative high reg pressure, and low hammer spring force, and...

    barrel harmonic end goal?

    We I have often thought about that. If we compare it to stretching a guitar string, the frequency will increase as you stretch it, and at the same time it will swing less. Trying to hit a faster swinging node is probably a litle more difficult? But at the same time will be a litle more...

    Easiest-Most Difficult PCP's to Work On?

    Some guns which need alignements of some parts when reassemble might be a litle tricky. Guns like FX impact, or wildcat, to some degree, can be "screwed up", if not knowing some measurements. Think the FX crown is easy in that regard, as I can not remember it is nesesarry to do any alignement...

    Easiest-Most Difficult PCP's to Work On?

    No matter the gun, it gets easier if you have tutorials, like on youtube, and how well they are made, than looking on a drawing. Of the guns I own, (some FX's, a taipan, and an agt vulcan 2) the vulcan 2 is probably the easiest one. The main thing being it has side covers, and when you remove...

    Costly mistake in buying a pcp rifle

    Since you already know how to change the O-ring, you only need the right size. If you do not know the size, you can measure the diameter of the bottom of the grove ( presuming the O-ring fits outside the part), and the with of the grove. You have then roughly the the two measurements you need...

    I never need to clean my barrel -- am I the only one?

    If it is a relative new gun, and if I am in a tuning procces, I do clean the barrel once in a while "just in case". I do that simply to rule out a dirty barrel being the cause, if I am not happy with grouping on target. If I see no improvement before and after, I then learn that particular...

    barrel harmonic end goal?

    I am not an expert, but on aiguns we change the harmonics by simply changing the velocity of a given pellet by lowering or increasing the hammer strike. If we only change the hammer strike force, we change when the pellet leaves the muzzle after trigger is pulled. But we also change when the...

    How to prevent rust on airguns?

    Well I see some has quiet different challenges compared to where I live:) To be honest when I saw Shinynight`s picture of his liner, I got a litle scared. I went and checked some of my liners I have not used in a very long time. I have never thought about oiling them after use, and lucky me I...

    How to prevent rust on airguns?

    I sometimes wipe my guns outside with ballistol. The main reason being they somethimes get wet if it starts raining, when I am shooting. But since your liner has started to rust inside the barrel sleeve, I would guess you store the gun in to high humidity? I have so far never seen that on any...

    FX Fx impact m4, why did they got rid of 1st reg?

    Good point. It could also be that the maverick was the first FX gun with two regs, being introduced before the M3. Since it also had a big plenum, it allowed for lower regpressure for the same power as other guns needing higher pressure. Not long after the Maverick the M3 was introduced, with...

    If you store the gun in warmer temps than you shoot it, temperature will also have some influence.
