For an MP5 he would have to spend over $20,000. The Title 3 permit would be $200 and would take over 6 months to clear with the FBI.
For the price, he could get over 20 rifles or pistols, and all of them would be more reliable than the MP5.
MP-5's are currently in the $13,000 to $16,000 dollar range, they are still a couple of years away from 20 grand.
There is no "title 3 permit". There is a $200 Tax stamp to process a Form 4.
I just had a transfer go through in 31 days, a far cry from 6 months. And the FBI only checks your fingerprints, everything else is done by the NFA branch of the BATF.
MP-5 unreliable? I can say without any shred of doubt that you have never fired, or probably even handled, an MP-5 if you think they are unreliable.
To the thread starter, your friend is going to need deep pockets, and a CLEO willing to sign the Form 4's for him to do this.
I have a fair amount of time on an MP-5, and I can only begin to guess why people are paying these ridiculous prices for them.
They are neat and all, but that kind of money can easily get 2, or even 3 transferable MG's in all manner of calibers. With some careful shopping one could get an UZI, and an AC556 for less than the cost of a single MP-5. And with a couple of conversion kits could be shooting four different calibers out of just two guns!
