Slightly leaky V12. Either the poppet is staying open or it needs a new solenoid. $30 fix vs. $60 fix. In a Bushmaster Carbon 15 (ICS) body. Battery wired to the buffer tube. Selector switch doesn’t work. Just need to replace the little metal disc on the inside. Stock version came with a plastic one that cracked. V12 was a tight fit, so one upper receiver loop wouldn’t fit in (2nd pic). Charging handle doesn’t retract on its own. Have to pull it out then push it in. Doesn’t affect performance. Still shoots with the leak. $265 shipped - HPA version (Valken V12) $135 shipped - AEG version (with ICS v2 split gearbox, works flawlessly) $235 shipped - V12 in Valken body instead of Carbon 15 (listed separately as well) 7.4v lipo and charger included with HPA purchase.
