The Revolution Fixed Barrel Spacer replaces the spring on Revolution silencers to lock the piston from traveling when the suppressor is used on a fixed barrel firearm. The spacer should only be used on a fixed barrel firearm. Additionally the piston with spring should only be used on non fixed barrel firearms as using a sprung silencer on a fixed barrel firearm will cause damage to the suppressor.

Features :

• Compatible with Optimus, Resistance, and Revolution series of suppressors.
