'Mk18' style AEG Build

[MrTea]

Hi all. I have someone interested in buying my custom 'Mk18' style AEG but haven't a clue what to value it at. Can anyone throw out some prices what they think it's worth to help me out? Details below;

**EXTERNALS**

Specna Arms Polymer Receiver with RRA trademarks.

Nuprol Bocca Series 2 handguard 12" - Bronze.

Magpul CTR style stock.

4x Tan Battleaxe mid-cap magazines.

KAC style 3-prong flash hider with QD suppressor.

Tan AFG.

Polymer folding iron sights.

RIS rail QD sling mount.

Raptor style charging handle.

Generic sling plate.

**INTERNALS**

Perun Hybrid V2 MOSFET - wired to deans.

Quick change bearing spring guide.

M100 Spring.

Maple Leaf Macaron 60 degree bucking and Omega nub.

ZCI Cylinder.

ZCI Cylinder head - double O-rings.

ZCI Piston - 14 teeth metal rack.

ZCI Piston head - 6 vents.

ZCI Aluminium Nozzle with O-ring - 21.4mm.

Standard Specna Arms 18:1 gears. Re-shimmed & Re-greased.

SHS High Torque motor.

310mm ZCI 6.02mm Inner Barrel.

The person has seen the pics and a video of it firing and is very happy with the semi trigger response and ROF but won't make me an offer for fear of low-balling and I have no idea what it's worth.

Apologies for any shoddy formatting, I'm posting on mobile.

Ty.

That looks like a nice job, it's all sensible stuff, and I'm seeing something like £300 in total parts on top of the base, right?

The thing is, they're replacing the standard parts that probably slung BBs about 80%-90% as well.

Comparing against new, the cheapest Specna EDGE 2.0 with a decent MOSFET are now £260 and up... but the unbranded Double Eagles with FCS are £190.

If I were selling it, I'd ask north of £250.  If I were buying it, I'd offer south of £200.  Other price points and compromises are available.
