New Condor Bounty Hunter without threaded muzzle ?

Hi , I just received a Condor mod. Bounty Hunter (http://www.pyramydair.com/s/m/AirForce_Condor_Bounty_Hunter/1968), the problem (not so big 🙂 is, that it is writen in the advertisement, the muzzle will be threaded. In my case , I receive the flash suppressor and the thumbhole stock (they come separetly packed from the main box with the rifle) , but there is no muzzle on the barrel !?!
The serial number of the rifle is : BC04686
I am from Bulgaria, and the rifle was ordered from USA. I will not send it back..the procedure is too long for me, but can You help me to establish (and to calm down my anxiety) is this only a “simple negligence”, or may be the rifle is from an old batch, and they simply put the additional accessories with it ?
p.s: I didn’t found anywhere in the net info about which dates of production corespond the different serial numbers series. 😕
