The Perfect Shell

Easy install into the Mk18 NGRS. Is holding up in a fully upgraded build with zero issues, this is my second one and will put them in all of my NGRS builds in the future.

Prommy nozzle, piston head, cylinder head, gears, spring guide
Eagle6 M120 spring
FPS Softair piston and tappet plate
Lonex cylinder
Paragon bearings and brushless motor

Sounds amazing and is very consistent at 1.52 joules!
