A very rare completely custom Kingdom of Airsoft (if you don’t know who Sam Liggat is, he’s the world renown NGRS tech located in the UK. Upgrade services by him are back logged for close to a year). The base is a Tokyo Marui NGRS M4. Externally it’s fitted with a rare Noveske receiver set with trademarks, a bronze DD MK18 rail, Prometheus gearbox locking pin, a VFC custom stock for large batteries, a custom pistol grip, flip up iron sights, a Magpul AFG, and a PTS flashider. Internally it’s been meticulously upgraded and polished to preform up to the KOA standard. Very crisp and clean cycling!! In the gearbox we have: - polished piston rails - radiused GB - perfect shim job - sorbothane pax for shock absorption - AOE correction - Prometheus Piston - Prometheus Piston head - Prometheus ball bearing spring guide - Prometheus CNC gear set - Prometheus Air Nozzle with o-ring - Lonex Aluminum Cylinder head - modified tapped plate - steel 5.9mm bushings - custom cut spring - BTC Spectre MOSFET - direct deans wiring - custom KOA motor upgraded from an ASG 40K motor - gold plated motor connections For the barrel set up - Prometheus 300mm 6.03 barrel - r-hop patch installed on barrel - custom KOA M nub for better range and accuracy - Prometheus purple modified bucking - Full Metal hop-up chamber fitted perfectly This is a very rare build done by the best NGRS tech in the world. Built for the player/collector who simply wants the best. Recoil works great and bolt catch also works great. I have 8 mags for sale separately, it comes with one. Eotech (real) not included. If you have any questions let me know! NO TRADES! Thank you.
