E-shooter Flare smoky insert for 5ku Putnik supressor

I wanted to use my e-shooter tracer/chrono/smoke unit but didn't like the aesthetics, hence the coupling with a 5ku putnik (afaik the only ak like tracer that fits the smoky) of course the Putnik is a beast in diameter so I had to improvise a design to fit the eshooter inside , centered and rigid. this design is the result of that and with the help of 2 stretchy o-rings the unit doesn't move a bit inside , even when shooting with an gas blowback replica.
