Kricket’s shroud problems.

Hi there!
I recently bought a Kricket. For the very first shots I realized that something is wrong with the gun…The groups are not so bad but for some reason i hade one or two flyers in each group…
All these days the weather was not the best possible. I was trying to find the ideal conditions to do a proper test before i take the final conclusions about the gun. I wanted to try all the possible scenarios to be sure that no fault of the barrel, or the pellets, or the scope, or me!
Eventually one of my tests I took the shroud of and try a group. And then the big surprise. A tiny hole group at the 30 meters. Similarly, the second, and the third and fourth.
I took a look through the shroud and saw the hole from the buffles were not concentric. Was badly finished or had poor construction.
These are a couple of photos.

and here are some photos of groups after the shroud repair.
