Tokyo marui NGRS mk18. Fully upgraded internals and shoots like a damn beast, RPS is quiet mental for this type of system so only use 7.4v batteries. can hop heavy ammo and swiftly lifts 0.3G bbs with ease 

One issue to note is the bolt stop is missing but that’s it ! Have a spare one if needed 

Upgrades and features:
-BTC spectre MK2 Bluetooth NGRS mosfet
-Tokyo marui samurai cobalt motor
-ZCI NGRS gearset
-FPS spring guide
-FPS spring (around 300fps set to heavy ammo)
-FPS full steel rack piston
-FPS piston head
-FPS cylinder
-FPS cylinder head with hard pad
-FPS tappet plate
-FPS nozzle
-Prometheus inner barrel
-Laylax red bucking and nub
-madbul or g&p MK18 rail
-PTS ERG grip
-PTS EPS stock
-Laylax gearbox pin
-Laylax steel barrel support 
-noveske receiver set
-Laylax outer barrel

As you can see this has more stuff done to most fully upgraded NGRS platforms and really packs a punch

The mock gas block pictures comes with the gun, i forgot to add it when installing the rail but doesn’t wobble its for looks (Daniel defense style gas block)
