Very light and durable. Shots 1000 bb's in an A&K PKM and looks like out of box.
I bought one at first, fut I was so pleased with it that I ordered another two. Very durable!
I installed one of this on my CYMA AEG, cause it had a piston with plastic teeth that worn out. This piston is working like a charm. Remember to use some teflon grease for the teeth, and silicon lubricant for the cilinder
