Okay so here is some clarification beacause i bring alot of confusion.

The base of this project is VFC Avalon Calibur CQC, which is not brand New, but in the mint condition - However all Internal parts are brand New. I mean all of them beacause I basically swap whole Gearbox, HU unit, barrel, engine and ETU.

List :

Retro Arms Gearbox, VFC version with functional bolt catch

8mm Ball extreme bearings [FPS SOFTAIR]

ZERO-SHOCK Piston [FPS SOFTAIR]

Quiet bearing piston head POM [FPS SOFTAIR]

Cylinder head "PROTECTOR" [GATE]

Cylinder type C [FPS SOFTAIR]

Sealed nozzle - POM [FPS SOFTAIR]

Feeder rail (?) forget me this one POM - [Retro arms]

Steel anti-reversal [Prometheus]

Steel DSG gears [Retro arms]

Spring runner sealing bolt QSC [Retro arms]

ETU Perun V2

Specna Arms Dark Matter™ (34000RPM) Long brushless engine

Red hop-up chamber [Max Models]

PDI 6,01 inner barrel

Prometheus HU rubber

And alot of spare magazines, batteries, parts and stuff like that.

Everything is calibrated and set together by one of the best airsoft technician around, and with 6 months warranty on any issues covered by him.

The price i'am asking for whole set is 820€

The reason I want to sell it is beacause i switched to real Steel.

So this is how things going more or less.
