Kelly is a good guy. Any problems with the K1 or GK1, just ask and he will help out. He is THE MAN on Huben guns.

P3 has original 70cc plenum but can add 2 extra 22cc extension for total of 114cc. Anybody done the plenum enlargement?

RTI has RPB barrels made by LW with very light choke designed by Gregor Kamensek in their Prophet 2.1 and P3 air rifles. The barrels are designed to shoot both pellets at high fps and slugs at even higher fps.

There is never a FINAL VERSION of anything. If you goto www.krazcool and scroll down, you will notice a "shorty GK1", and if there is demand, it might make it to production run. There are also tons of carbine stocks and replacement handgrips. There is also a version made for the Wolfiek group...

The 4th run thing is because these guns are produced in batches of a certain number and distributed to the authorized dealer all over the world. Huben makes the certain number of the GK1 according to the number committed by their dealers. If big name US companies orders 10k pieces then that...

These hammerless guns likes heavy pellets. Make sure the pellets are not clipping the moderator. Clean the barrel.

Getting a chrony will help a lot. Most likely you are shooting the pellets too fast, pass 950 fps. Get the pellets to shoot 850 to 920 fps. HTH.

As well known by the owners of Huben air rifles and pistols in both calibers from 2020 onwards, they are manufactured using Huben made barrels that are incompatible with normal sized slugs. Both calibers are ovesized but they work well with heavier pellets. Gregory has designed V2 boattail slugs...

A little imagination, perseverance and innovation was what Gregor did to transform the K1 to the GK1 - G in front of the K1 as acknowledgement of Gregor's work. To the OP, please imagine and try to achieve what YOU can afford to realize your dream air gun.

Based on what Gregor has researched, the .22 needs .222 , .223 and the .25 needs .254 , .254 for accuracy.

Be careful to insert back the teflon flat seal in the blue housing and NOT over tighten the fill probe. If it leaks tighten more until the leak stop. If overtighten the teflon seal will flatten and seal off the hole.

Yes its normal to ship pcp with near empty tank. Unscrew the quick disconnect from the blue filter housing and compare the threads of the fill probe. If they are the same then screw on the fill probe to the blue housing.

Has anyone tried to encase the barrel with carbon fiber tube like how fx does it to strengthen the barrel and improve barrel stiffness?

Heard that the Vulcan 3 700mm barrel are made to shoot slugs.
