Hi,since I get my Cricket Tactical 60, 6 weeks ago , I had some accuracy issues : POI shifting up , down , left and right and pellets velocity was inconsistent. So I decided to find out what was going wrong.

First I put a Huma regulator , which I set to 115 bars.

I improved the action somewhat by polishing some parts , and adjusted the trigger to make it lighter.

Now , I think this was maybe the most important part . The barrel of the Kalibrgun has a little dent , set at exactly 180 degrees of the barrel port . When fitting the barrel , this dent must be seen through the front screw hole in the picatinny rail . This means that the barrel port and the transfert port are exactly aligned. Despite the fact that the barrel is clamped by 3 or 4 allen screws , I noticed that it could rotate a bit when the shroud is overtorqued ; that happened on my gun . I also noticed that the screw which should keep the barrel in place was a bit too short , and doesn't touch the barrel . Moreover it had a flat nose instead of a pointed one ; a pointed nose means that the point of the screw engages the dent of the barrel , so the barrel doen't rotate when fitted . This was explained in an ernest Rowe video. What I did is changing the factory front screw by an homemade , longer and pointed one. Care must be taken to be sure the screw engages the dent and tightens the picatinny rail at the same time , so srcew lenght is crucial . The drawing below will make the explanations clearer ( I hope ) .

Here is the first shooting after all these modifications , and I'm pretty happy with the result , even if I think that accuracy could be improved a bit ...

The Crickets do not come with this pointed bolt you speak of. There is a barrel locating set screw that is pointed. It is used when installing the barrel. It is then taken out once the scope tower/barrel clamp is tightened and is replaced with a normal bolt. 

I do hand it to you for creating a cool bolt that bottoms out in the barrel dimple and tightens at the same time. However, this isn’t a factory set up.

Hint - DO NOT tighten your new pointed screw too tightly. In tightening it too tightly, this can actually put enough pressure on the outside of the barrel, to effect...the shape of "inside" of the barrel. Maybe this is why, as ZX10 notes, Kalibrgun removes them after the rotational indexing is complete. They apparently understand the engineering situation.

So, tighten with care.

Thank you , Bigragu.

You're right Keyman62421 , I find Kalibrgun more consistent and accurate than other well known brand.... know what I'm talking about:)

I just wanted to say that my Tactical has some issues which have to be fixed . That happens from time to time , even with high priced guns. Otherwise , all my others Kalibrgun were pretty accurate and consistent out of the box ...and ..yes the Cricket IS very heavy.
