Build Spotlight: S&T Sterling AEG
Check this wild card out, a British Sterling SMG made by S&T Armament. Featuring a split type proprietary gearbox, nozzle, tappet and hopup, and nearly no guides available online for disassembly, this is an amateur technician’s worst nightmare.
The most interesting part of disassembly was definitely the tappet-plate-dislodge from its track and bent upwards into the piston area to clear and extract the split gearbox from the cylindrical receiver.
Some typical buried screws and pins were all that was stopping me from overhauling this with a new SHS piston set, high torque motor, Maple Leaf bucking and Mosfet.
It took a concave nub well and despite the proprietary chamber is compatible with marui barrels, buckings and nubs.
The second most interesting part was that it’s wired backwards (?) in the sense negative was wired into the trigger contacts and both positive wires going to the motor.
After double checking the gear rotation it was normal and the new motor dropped in fine with a standard wiring. It’s extremely peculiar why this wasn’t wired normally, i’ve never ever seen a gun wired this way from factory. However it’s still a chinese made one off world war replica, in that genre it’s not even the most surprising thing i’ve ever seen. A lot of these models you just have to hope are Somewhat aftermarket compatible, and be happy with that.
The whole build was buttoned up and worked right away. It’s at 375fps .2g with a new bucking, the air seal is good so i left the spring stock and my client is happy.
It’s also got a one year warranty.
