Congrats, I know you'll be very happy with it.
Here in the US that will cost ten times more, around low $20K up to the high $20K and only available are pre 1986 models, '86 and after citizens was banned to own machine guns.
We have the same upper forge marks on my Colt never issued USGI M-16A2 upper half I got way back in 2005, "C M" for Colt Martin Marietta, also have same peel washer of the flash suppressor.
New never issued Colt M-16A2 USGI uppers was plentiful here in the US after the ban expired in 2004 and also the year later 2005 and at a good low prices.
On your list of available full auto rifles lots of good models there.
I've got semi versions of the Steyr AUG rifle and carbine, IMI Galil 16" barrel carbine, and IMI UZI model B carbine, I wish I had more money to buy at least one full auto rifle.
