Trident Rotary Hop Up Unit

A polymer-made rotary hop-up chamber manufactured by Krytac for their AR-15 and LMG series of airsoft replicas. The hop-up unit features a precise, numbered adjustment wheel, retained hop-up nub, and top access through a lever arm for service and maintenance. The product itself is used as an original equipment for Krytac replicas. Still, it is also compatible with AR-15s made by other manufacturers.
