Angry Gun dummy suppressor/barrel shroud to fit Krytac Kriss Vector, slides over the outer barrel and secures via a grub screw which holds it on securely.

This is the dummy version and doesn't include the tracer unit.

Can also be used with the KWA Kriss Vector, but needs to have a shim added to the barrel as the KWA outer barrel is a slightly smaller diameter. (I cut a strip out of a coke can and wrapped it a couple of times nice and tight around the outer barrel and it worked a charm.)

Doesn't seem to be anywhere over here selling these right now, imported you're looking at about £60 plus postage and plus import duties, I'm wanting £45 posted and paypalled.
