Yes my cricket was leaking, I sent it back they fixed but is not giving me the speed that he said, but is only 28 fps slower than what i was told.. and my daystate has been dropping fps a while ago I sended to Airguns of Arizona to be checked and they told me that it was shooting 820 when I bough it it was shooting 840, now it is shooting 790fps so that means that is getting worse.. I got a new chrony to make sure that wasn't me doing mistakes,, I did a test puting a little piece of paper on the bridge and it fly away when I fire the pellet. Anyway I will contact AOA .. thanks to everyone for the advices,I'm new to the airguns hobby, I have a lot to learn..
