a-5 with no serial #!?!?

so i bought an a-5 off of ebay.  I went to check the serial number when i got it, and I noticed that there wasnt one...  The powder coat on the gun looked a little sloppy so i figured that it may have just been repainted and the serial may have gotten filled in.  I polished off the paint in that spot and theres definatly no serial number there.  What up with that?

no picture, but i dont think they were milled off, as that whole section is uniform, from front "mp5 stump looking thing" to the rear grip, and to mill them off it would leave a noticable difference in reciver thickness...

He probably changed the left reciever.

Hmmm... sounds to me you have a contract gun, probably once used by the CIA, with all identifying marks removed as to allow for deniability.

Or as mentioned there might have been a problem with the reciever half and it was replaced by warranty (or repurchased because the previous owner did something dumb like try to pry the halves apart without unscrewing them). In that case they may send out a shell without a serial number, but a call to Tippmann would probably be needed to confirm that. My guess is that replacement shells probably are not stamped to prevent the purchase of a new shell half being used to disguise a theft ... on the other hand that's exactly what might have been done anyway - buying the shell half to disguise a theft.

Maybe he took 2 left recivers and put em together so the serial and warning **edited** is gone. can you still see the warning engraving on there? if not, i bet he put 2 lefts together and filled in the hole where the cocker would be? idk, does it make a huge difference? as long as you can use it....
