Due to a lack of use I'm selling my SGR-12 along with the Tokyo Marui drum mag for it.
It has an RPS of 12 per barrel on an 11.1v LiPo. I've 3D printed an extension to the battery compartment since it is fairly limited stock.
All 3 barrels have an adjustable hop-up so one can adjust the BB trajectory as desired.
The drum mag is filled with BLS 0.28g BIO BBs and it uses 4x AAA batteries.
