G&G TR16 dmr klasse 2 ( 500fps/ 2.1 joule)

I am selling my G&G tr16 dmr class 2 due to purchasing an hpa sniper. This has been upgraded by the airsoft shop in Poperinge. Upgrades include:
455mm 6.03 prometheus barrel
Mr hop rubber (freshly replaced)
Maxx model m4 hop up
Gate titan v2 advanced set
Maxx model cnc hardened stainless steel cylinder 450-550mm
Guarder aluminum vent piston head.
Sp140 spring from guarder.

This has a 2 second delay set to comply with regulations with most fields. This shoots about 2.1 joules with .4 bbs. There are a total of 9 mags of 40 rounds and an Odin adapter with this DMR. 417 pouches in multicam can be crossed for an additional charge. Accessories are included (novritch scope 3-9x zoom and a red dot from aim o). There is a piece of paint missing from the replica on the magwel on the g&g logo due to a defect in the paint. It just fell off. This cost around 1300. I want 700 for it. Also be open to an exchange.
