Hi guys this is my SPR build, I usually put the semi lock on it so Im allowed shoot 2.3j at the field, If not I just use the stock m120 spring. the semi lock is the tapped hole you see next to the selector switch.

what is has:

-18:1 ZCI CNC gears

-Maple leaf MR.Hop 70deg

-Mad bull 6.03mm with around 400mm length (cant remember)

-bushings (to handle the heavy spring)

and a 3d printed "suppressor" barrel extender to protect my inner barrel.

-Perun Hybrid v2

-new tappet, piston, and nozzle

-shimming

The only two internal things that are stock is the Motor and the gearbox shell (both cyma) which I know I need to change ASAP. Planning on getting a retro arms shell and a higher torque motor
