Gutisbits Mistral end can and DB killer.

Ordered from Gutsibits a Mistral Tria end can which fitted nicely and imo looks better. However it cam with a DB killer which I might fit if I could work out how? There’s no instructions and i can’t see anywhere to fit it. Any ideas anyone?

On some silencers the DB killer goes in the font of the can, other to the rear. You may find that the DB killer restricts the performance - assumption made that this is a secondary DB killer.

Its the one that came with the can and the illustrations show it at the rear.
