Unicorn Airsoft's 50 Degree Rubber Hop Up Nub replaces the factory nub in standard airsoft hop-up chambers. It presses against the bucking to apply backspin to the BB, and a 50 degree rating is soft enough to suit lighter BBs and lower velocity setups. The rubber construction grips the projectile without deforming it too much, which helps stabilize the trajectory for tighter groupings. It installs directly into the hop-up unit without tools. This item ships as a single nub and comes in black.
