I hated cleaning it, mostly. Which we did for hours. Our drill sergeants found it particularly funny to pull out a snow-white wipe to demonstrate that some residue could still be found somewhere after n hours of cleaning. The plastic blank cartridges we used were particularly hated for leaving massive amounts of hard-to-clean dirt.
The purpose of the weapons during my time in the military was to be tools of harassment by the sergeants and officers. I could not have cared less whether they were actually good for any defensive purposes.
