I have 2 of the 3. KG
in .22 & .25 as well as the Veteran in .22.
The GA airguns Power Tunned .25
is mouse fart quiet for sure using a Sumo. Without the Sumo is really not very loud at all. But yes, mechanical noise at your ear is a bit loud. Only you will hear this though. I have not shot it to 100, but folks that do are hitting small spinners at that distance. At 50 yards it’s a ragged hole.
The .22 Mini Carbine
in .22 is my favorite, but it’s a .22 and you are looking for .25. AoA claims to have them in .25, but I don’t know if this is factual and if so, how they perform.
The Veteran has a few things going for it. I’m no trigger snob, but even Ernest says it’s the best trigger out there. To me, they both are equally good. It is a chubby SOB. Very quiet. One of the nicest features in my book is the anti double loading. That being said, I never shoot it, don’t know why. Except I always grab my Mini.
I think between these 2, you cannot go wrong. If you choose the Cricket, I highly recommend GA Airguns. Superlative service and integrity.
