Waldo Dynamics "Hush" Silent Fill Valve O-rings

Annoyed by gas spilling everywhere when filling your GBB mags? Then Hush is your answer!

Once these O-rings are placed over your fill valve you will be able to silently fill your magazine without causing any gas spills. This is a renowned inconvenience for some brands of GBB's, more specifically TM (but will work in competing brands).

And of course, they come in a charming yellow.
