AirMaks Arms Krait owners speak up

@Silent shot - I also have a Krait standard in .177. I shoot mostly H&N Baracuda Extreme Hunter in it at 1030fps. I also shoot 10.03 4.51mm KO slugs as well as JSB 10.03 pellets. The speed drops on both, but I just adjust my scope (I have a digital scope on the gun so I change the profile for what I'm shooting) and go about shooting. My gun likes the KOs and is very accurate with them, but not "target competition" accurate! I shoot pests with this gun out to 100 yards - smaller ones like squirrels, rabbits, and starlings and have no problem dropping them in one shot. I use the Krait L .25 for longer and larger pest shots.
Thanks for those info.

Somewhere was that older krait should was made for pellet use.
Some point they chance choked should for slugs use.

Are those both with MK4 or MK3 regulator?

They are very accurate with slugs, but hard to know how exactly well they work with light pellet.
 
@Silent shot - My Krait Standard 177 is Mk4 and my Krait L 25 is Mk3. Again, no problems after I had the first reg replaced after I turned it the wrong way trying to tune it! The only difference - other than the threads - I believe is the way you turn the reg. It's a lot easier with the Mk4. I use the bent nose pliers and didn't buy the tool...

Krait standard 0.22 is really interesting rifle.
Is light & short and shoot well.

I was confidence that those regulator problems was solvet with those mk4 reg.

But now i don't know how it is.
Really like to buy one, but for my luck it can be bad one?

All things in youtube is not 100% true, but can that comment be right.

Is that reg really with some wrong parts after huma-air?

I loved mine initially but regulator issues (MK4 Reg) forced me to swap it for a Panthera.

I've had an AirMax Krait air rifle with the a MK4 regulator from Huma (the one with four holes for the adjustment key) for several months now. Unfortunately, from the very beginning, the regulator had severe creep issues. I was disappointed with the rifle and even considered returning it, even though I really liked it. I knew that earlier versions of the regulators and monoblocks had problems with creep, but my version was supposedly free from this defect.

Unfortunately, I was badly disappointed because mine also suffered from creep. I suspected there was an issue with the regulator. So I ordered a spare regulator from the Huma store. After replacing the regulator with the newly purchased one, the creep problem still remained. I disassembled both regulators and examined them - they looked perfect, yet they didn't work properly.

I then ordered a repair kit for this regulator from Huma, as well as two additional disks separately. I received a repair kit in one ziplock bag, but half of the O-rings didn't match my version of the regulator, along with two original beige disks. In the second bag, instead of two more disks for the Krait, I found O-rings for the FX Gen 1-2-3 and two disks for FX. I was a bit annoyed by this.

I began replacing the O-rings and disks in my regulator, but there was no improvement - the regulator still crept terribly. Out of curiosity, I finally installed a disk from the FX, and it was a bullseye. The regulator came back to life. There's absolutely no creep now, and it's very precise.

The original disk in the regulator is beige and has a diameter of approximately 4.10 mm - 4.13 mm and a thickness of 1.37 mm - 1.42 mm (1 measured two disks). The FX disk has a diameter of 4.08 mm and a thickness of 1.05 mm, and it is white. It seems to me life. There's absolutely no creep now, and it's very precise.

The original disk in the regulator is beige and has a diameter of approximately 4.10 mm - 4.13 mm and a thickness of 1.37 mm - 1.42 mm (I measured two disks). The FX disk has a diameter of 4.08 mm and a thickness of 1.05 mm, and it is white. It seems to me that the original disks are too thick and don't allow air to pass properly through the holes in the side wall of the regulator cylinder. Huma should take a close look at this, because it appears this is whe
re the problem lies.
