Besides of a lot of small modifications, its basically:
TM AUG
7mm Hurricane mechbox.
Aluminium Piston "Costum Helical".
SP170 Spring.
Leapers 44mm Mini M3 type scope.
Leapers 30mm Medium mounts.
KM 509mm 6.04mm Precision Barrel.
Systema TU Engine.
Systema Bore Up set. (Nozzle, cylinder, cylinderhead and pistonhead)
Systema Ultra Torque gearset.
Systema steel bearings.
BestGun AUG-RIS. (black)
PGC AUG Hop-Up.
Guarder Hop-Up bucking.
KM Hop-Up "Roll".
KM AUG-P set.
TM Knights Type Pro Silencer.
LayLax Pro Silencer Adaptor.
2.5mm wiring and JSL Mosfetsystem.
Internally 10.8V GP2000 battery.
.
A couple of "selfcutting" screws(extra stability), small amounts of 60g paper and Teflon tape, to fixate the barrel.
Its put together by one of the most competent danish mechs, and the current setup has seen less than 200 shots. There has gone a LOT of hours into putting this rifle together, and its pretty much as perfect as it will ever get.
When all comes together the "new" price on this rifle is on the wrong side of 1400€, and a new one would take more than 20 hours to put together.
All of the AUG`s known factory flaws and weaknesses have been fixed.
Also in the package is 900ish .30 bb´s, 2-3 std mags and 1 highcap.
I'm thinking a price of 650+€, but make an offer. I'm also interested in a fully upgraded and modified Tanaka M40.
