I am finally selling my sr25. I love this gun, but I just don't use it much anymore as BARs are more fun for me. The only thing in this that is still stock is the gearbox shell and cylinder. Everything in the first picture goes with the gun. 3 hi-caps, old barrel, acog, mag pouches, and the riser. Here's my parts list M140 spring Matrix godzilla high torque motor SHS high torque gears (don't remember ratio) Angel custom tight bore barrel Mosfet G&G hopup assembly Prometheus bucking Alumimum h nub Alumium piston Upgraded spring guide Alumium piston head with damper Professionally shimmed
