Big Dragon 130mm Silencer (14mm CCW)

Silencers in airsoft are primarily an aesthetic choice - in 90% of situations, they don't do anything (except make the gun look damn cool). That said, many people use them to run an extended inner barrel, or in the likes of HPA setups, to take out the higher pitches of the gun firing.

This silencer is 130mm, constructed out of metal, and is 14mm CCW (counter clockwise). It is important to make sure you're screwing the silencer onto your rifle in the right direction as otherwise you can destroy the threads on both your gun, and the silencer.
