well enough of a video to show what the trigger is like to take apart. I still don't know what is wrong with mine after taking it apart about 10 times to change o-rings, replace plastic parts, etc. Everything looks perfect but it is hissing air out the trigger and refuses to work. I have the sleeve, piston, bumper, head, nose off and checked everything after I couldn't find the problem in the trigger.. Ugh. Bought a NR83A5 to use while I fix my A3
