"Sorbothane cylinder head pad, supplied with a protective shield. It simply glues onto the cylinder head, improving the reliability of your AEG in two ways:
Sorbothane is a visco-elastic polyurethane with excellent shock absorption, shape retention and sound dampening properties. It is made in a variety of hardnesses, 70D being the best mix of shape retention and shock absorption. It is probably the most cost-effective upgrade you can buy for your AEG.
The pad is 8mm thick in total, which should give you perfect AOE in most guns."
