It's a hop up spacer. Or nub, if you prefer. What more can I say? Very nice, very soft (which is good).
Most hop-up buckings come with these, but this is a good replacement if you happen to have lost your spacer. If you're ordering something else, throw one or two of these in, just in case you lose that spacer in the future. (Take it from me, playing without a hop-up for half the day is not fun.)

Its sad that I'm writing a review on a piece of rubber that is about 4 milimeters wide, but anyways.
These work, but its not really worth the wait and the shipping charge, when you can go get a piece of rubber, and cut it out in roughly the same form, and that would work just as well.
ICS is a good company, and I'm sure this would work just fine.
