NO REGULATION !?!

Cold weather drastically effects all my regulated guns. Only one is only minimally effected. That is my Lelya. I am now looking for a cold weather gun for just this reason.

I'll say give AEA a look, they are not using regulator on their semi/full autos, because as you know the regulator have a recovery time, and that makes the implementation of a semi/full auto impossible, I think that's the reason Evanix is not using regulators, just not possible to implement.

AEA has a really impressive video where they explain the reason why they are not using regulators on some of theirs guns, take a look a this shot string

Also I remember, the guy from Rusia that won last year EBR (Nikolay Boldov) his rifle was not regulated, and he designed the rifle specifically for competition, and was the huge variations on regulated pressures during winter, the big factor that Nikolay used to decide not to go with a regulator.

I watched that video when I was considering my AEA. Needless to say my AEA is fun shooter but it doesn't get strings like that. I get almost a whole mag that is similar but then it just drops off. Though mine doesn't have a bottle but one of the small air tubes. But either way I really like my AEA.

this is low power edition.I used to have the same question when I bought my carbine.

AEA guy said. Dealers in the U.S. and South America ask them make huge power, so they can't be as stable as video. If you're willing to use 18gr pellet at 900fps, they can sell this version.

My carbine shooting 18gr around 1020FPS. I think its big power version.

some body use varmint. Turn down the power. You can see his speed. 40 shots around 930fps.It's very similar speed on the video，I think if it's lowered to around 890fps on the video, we should got the same result .

HubenK1, SK 19, FX Monsoon .... all this and more are semi/full auto regulated. So i'ts possible, Some companies are just worse than other, that's it.

Colder weather means slower molecyles and at absolute zero everything is on total stop thats where name comes from. At 68F speed of sound on air is roughly 1125fps but when we drop down to 32F we pass soundwall at 1087fps and if we go to 0F its only 1050fps. On opposite if we heat it up to 104F speed of sound will also increase since hot means more molecyle movement and cold slower and now we would be at 1167FPS to crank it. This ofc heavily effects on PCP airgun even if its regulated or not but might be effecting bit more on regulated one = slower recoverytime and less air volume to midigate energy loss from colder weather. 

Regulators in PCP rifles and COLD working better or worse is not true with most slowing down coming from other areas of the gun.

Cold effects all metals, plastics etc having them shrink slightly and this includes barrel bores !

Lubricants thicken increasing drag as well.



Regulators are not for every gun or application .. granted. But having false information circulate as to the OP's question serves no purpose either.

I've use regulated guns for years in winter here and never saw anything really different from any other unregulated gun I've shot. And it gets well below freezing here as well

You don't understand what that video says.They mean that when you shoot fast, you can't shoot accurately. so when you shot fast regulator is useless. Because regulator is for accuracy.

when you single shot the regulator will Reduce power. FX monsoon its very low power.

K1 is high power. but must 2700PSI is max power. So normally we filling 3600PSi can’t shot all magazine. So K1 need to filling 5000Psi can shot two magazines. 5000PSi need to add regulator.

SK19 as an imitator of Huben, he solved this problem with large capacity tanks.And its regulator space is very large, so it depends on the volume to solve the problem.

It is wrong to think that the shorter the recovery time of the regulator is the better. If the recovery time is very short, it means the Air connection, which means that the regulator has failed.

Technically, there is no difference between long recovery time and short recovery time.when you shot long range sometimes .power maybe more important. More power means more heavier pellet with same speed . So if you already got good accuracy why asking regulator ?

this is what the video mean.so these guy is very professional. They said regulator is easily to them. 

Our guns are all from AEA's Taiwan dealers. This version already with regulator , and the recovery time is fast enough, but AEA guy suggests that we throw it away.It shows that they have a unique understanding of regulator , is not a technical problem at all. 

by the way. Huben and AEA in same manufacturer. 

There are a lot of fantastic unregulated guns out there. Marauder, for example, is pretty good without one. A lot of those older platforms can shine, especially with a small tune like that Hammer-debounce device from Joe Broncato. Even in their stock form though, in the early 2000s a lot of unregulated guns were manufactured and engineered to function without regulators. I’m not for or against them, but like every tool you engineer there are times when a regulated gun is not as good as an unregulated and vice versa

This is the video at the exact location I was mentioning earlier on my comment:

Just can't find the part he explains the reason why he designed not regulated, I recall was because huge variations in temperatures was causing huge variations on the regulator pressure

2 years late but can I say something? I count psi on an unregulated gun. I count shots on a regulated gun.

help me to solve leaking problem.

@Hasan007 you will get more responses if you start your own thread and put what gun you have in the title. Adding on to a 2 year old post off subject will not be noticed.

I'm no expert, but I understand the basics of how these rifles and regulators work. I don't see why there should be any significant difference in the effects of cold weather on each type, as long as the cylinder or bottle pressure is well above the reg set point.

None of my airguns, regulated or not, work in sub freezing weather. I dont go out in that crap.

In seriousness, I've never noticed a change for the type of shooting that I tend to do in those types of conditions.

I have not had any issues with the regulator on my prophet in cold weather, but I think if I ever did I would just go to my camera bag and grab one of my velcro lens heaters and battery pack. Wrap it around the reg to warm it up.
I don't see why that would not work.



I use these on humid days to keep my lens from fogging, They can be had in various sizes for $20 or less on Amazon.

I agree with Rob in NC. My POI is constantly shifting when shooting in the cold. The guns and scopes do NOT like it. If backyard pesting in winter, I leave the guns in my house. And only go out to the garage to shoot when I see some quarry.
