Any of you guys got some spare time to turn me a custom thread adapter?

i am looking to put a airsoft barrel extension on my condor. The airsoft replica has 14mm cw threads and my talon has 1/2 x 28 tpi threads

is this possible and what type of price would i be looking at?

thanks

BTW i may be interested in more then one, got to get one for my condor too
