For all your daily silent killing needs there is a new AR-15 (M-16) version on the market. The PSE TAC-15 is a crossbow mounted on an AR-15 receiver.
“This crossbow is mounted on the skeleton of an AR-15 assault rifle and has a scope. A handy feature of the skeleton, by the way, is the “picatinny rail system.” Long story short is you can slide a grenade launcher in there as an add-on.
What millions of Geekologie comments fail to mention is how perfect this is for hunting vampires.
As such it is certainly on the short list of acquisitions for the VTK Biohazard Containment Service. Who on a completely unrelated note would really like to know the whereabouts of their good old buddy Don Henrie. Come on Don! Wave, so the spotlight knows where you are! Ah! UP THERE! *ZZZAP*
The outstanding picatinny rail system also helps with attaching a chainsaw bayonet which will come in handy should the zombie apocalypse in Europe become a threat for our german hive headquarters.
