Looking for other interesting AEGs (like PPSh) or GBBs. Here is a nicely upgraded Matrix SR-3M. It has 16:1 SHS gears, FMR piston, stainless SHS cylinder, and a SHS high torque motor. It is missing the stock button, so I took off the stock, as it would just flop around. Thanks for looking guys, and ask any questions you have about this gun.
