I used the truck nozzle once. Not much of a pop off either. havent viewd the restrictor with an eye to removal, but sure nothing some tin snips wouldn't tackle. I dropped a spring in my tank from a 5 gal can of bio, so if something falls, it wouldnt worry me., I'll get my spring back when I pull the tank screen.

Again, only noticed it once so far, the truck nozzle.
