Guarder Enhanced Cylinder Set for Airsoft AEG Gearboxes (Model: G36C)

"The air nozzle it came with was not compatible in my TM G36C.. Thought that was extremely odd considering these kits are made with TM as the set standard. In addition the stem for the piston head is way too fragile and snapped when simply installing it.. Had to buy a whole new piston head assembly because finding a metal stem on its own is impossible. Honestly, I’m highly disappointed with this purchase and cannot suggest it.
