Airsoft KAC Barrel Extensions

Airsoft KAC Suppressor replicas. Both have 14mm CCW threads for airsoft use. As always, use responsibly - these will NOT suppress any airsoft or actual firearm and will be destroyed by even attempting to do something that stupid on an actual gun (but you knew that - right?). Historical note: KAC never made a 4 inch suppressor (yep - I totally made that thing up!). I will post a 6.25 inch model if there's any interest (so let me know). Pic is of the printed/finished micro version mounted on an airsoft M4.
