Airlab sent in news that they have restocked on their Sorbothane Pads... "We've been busy working on our latest batch of sorbothane pads. After a long wait, they're finally ready to ship. At just £5 each, they provide the greatest benefit per pound of any upgrade. They protect the gearbox shell from cracking while also greatly increasing piston lifespan.

• Prevents gearbox shell from cracking by absorbing excess shock energy.
• Increases piston durability by correcting the angle of engagement (AOE).

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. At £5, it is probably the most cost-effective upgrade you can buy for your AEG."
