This square shroud allows your Vector 22 CRB to duplicate the visual aesthetic of the Gen 2/Gen 2.1 centerfire Vector CRB.
The square shroud is tailor made for a secure fit around the Vector 22 barrel.
When installing the barrel shroud, tighten the set screw against the divot on the underside of the barrel. Check this screw periodically to ensure that it's secure. We recommend degreasing the set screw and applying a small amount of blue threadlocker.
