In terms of using the right ammos, @Devink is correct! The following ammo types have worked well for me: JTS 22gr .22 pellets (harder lead alloy, stout pellet) HN Field Target Trophy Green lead-free .22 pellets (<9.6 gr!) GTO .22 lead-free pellets (expensive) AVS 22gr .223" slugs (2 MOA groups...

This happened to me a few times. Here is how I fixed the problem. Put the safety on! Completely degas the gun. There are a few YouTube videos showing how to do this. A jam typically let some air out, but not necessarily emptying the air reservoir. Remove the shroud using a 7mm hex key to remove...

You're welcome! I also found that it is more effective to apply 30 weight silicone oil directly on the 3rd stage rod and the inner portion of the first stage tube. Dropping silicone oil via the air intake hole does not seem to lubricate as effectively. To lube like this, only the top part...

Just received and installed this from Ethan Cobb today. The precision and workmanship of this bottom rail is impeccable. It is a precise fit on the trigger guard. I cannot be happier with this purchase. The rail is a milled aluminum piece, and it is stout! The Arca adapter slides in perfectly.

The most pronounced sound from the action is, surprisingly, the magazine cycling. The volume seems to correlate with the power level. The key to keep the gun quiet is energy level and a good LDC. I have tested the skinny (30mm) Huma, an oversized Clague, and even home-made 3D printed ones, all...

@primaz , I have no experience with the .25 version of GTO pellets. However, I can share what I know about the .22 ones. The GTO pellets are lead-free. They are light and made of a hard alloy. In .22, these pellets fit the magazine well and do not jam. Turning down the power setting, these...

That makes sense because the cross section area of a .25 is about 30% more than that of a .22. The current "happy point" (flattest shot string) of the .22 GK1 shooting 22 gr pellets is about 870 FPS. 870:700 is about 1.24, roughly agreeing with the 30% increase of cross section area of the...

The Dragonfly Mk2 seems to share the same basic platform as the Artemis PP900 guns. If the barrels are similar, JSB Exact Heavies are a good starting point. They have a relatively high BC. 12 FPE at a closer range like 20 yards will pass through a squirrel in a body shot using said pellets.

After much experimentation, I have come to the same conclusion that the GK1 is best shooting pellets and not slugs. Mine is in .22, but the issues are similar with the .25 version. As a last ditch attempt, I have ordered some .219 hollow base slugs from AVS. I am not holding my breath. Now...

I have the non-Canadian .177 version. After the barrel is cleaned up on both ends, the gun is quite accurate. The trigger group can also be polished, and have the adjustment grub screws replaced with one with a ball bearing at the tip. That improves the trigger quite significantly. The...

Thanks for the confirmation. The valve design seems to have an intrinsic flat shot curve at around 800 to 900 FPS, regardless of projectile weight. This gun, especially when unregulated, is definitely not for slow muzzle velocities!

@wimpanzee ,I am curious how you set up the power setting and the pressure range that you use. I have been trying to set up for shooting GTO pellets at a lower speed, but I could not get a flat or bell-shaped shot string. The shot strings that I have so far are always tapering down. I agree...

The thread is M10x1mm, male on the hose, female on the probe. This appears to be a fairly common size for foster quick-connect fitting, Amazon has it. Yes, the package includes a full rebuild kit. I contacted Huben before purchasing to make sure additional rebuild parts can be purchased. Check...

I just got some GTO pellets today and I just ran a chrony session. Perfect timing to check out the number of strokes to pump the GK1 back up! I shot the GK1 down to 200 bars. It takes 5 strokes to fill the hose to 200 bars. It took about 20 strokes to fill to 250 bars. Then 14 more to fill to...
