Done!!
After a long afternoon in the shed avoiding the wife/rain, its finished
Spec/mod list:
Old M14 barrel used as barrel extension
hand grip modified using 10mm copper pipe to give palm swell and finger and thumb rests.
home made silencer using baffles and foam.
400mm x 6.08 barrel, nubless TM rubber, Madbull fishbone nub.
Airbrake fitted to piston.
Bearing spring guide
M120 spring
Chi Com motor out of my old KART EBR
MOSFET and Deans
347 fps +/- 3 with a Excel .2s
12" groupings at 45 metres measured using .28 Guarders (when I'm feeling flush and the wind and rain disipate, I'll try again with SGMs
)
Still to do a paint job, but I want to play test it next weekend before I do that
