I can! I had one of those terrible gats as my first, and I can help by advising you upgrade! Until then, however, I can offer some advice: firstly, is it out of air? no? Okay then, remove the bolt and hammer and give them both a good clean and relube. Llift the bolt pin out and slide bolt out, then pull the small retaining pin out from the side, being careful to not let the assembly spring out everywhere, and make sure it's in the right way up (the flat side should be facing down) and check to see if the sear is stuck down (you should see it sticking up a bit, try pulling the trigger a couple times and you should see the noid popping it down). Let me know what you observe when you do this.
