CA36K (HK G36K/HK AG G36) KSK

I have here a Classic Army CA36K with Classic Army AG G36 UGL, the rifle is completely outfitted to German KSK Kommando Spezial Kraft (Special Skill Commando) configuration, the 3.5x optic/carry handle has been replaced by a flat-top rail with HK MP7 type front and rear sights, the EoTech 552 is made by Hurricane, (alone cost $187USD) and the sling is the real deal KSK issue made by TacGear in Germany, the flash hider is the KSK type, and the barrel length is between the "K" and "C" series weapons, the flip up sights co-witness the 552 reticle, all working perfectly, sprayed in woodland colours to match researched pictures of KSK soldiers, this gun was never skirmished, it was used to replicate a living history KSK soldier so a lot of detail was added, including proof and manufacturing marks on the AG G36 launcher, batteries for the 552 are included, so is the HK KP8/HK USP Compact Blow Back pistol - works perfect.
I am looking to sell or trade for any make M4A1 to the specification listed below, E150 lot.
Both 1 joule.

I am looking for a M4A1 with metal quad rail handguard, metal upper and lower recievers, metal barrel and handguard - and in decent nick.
