Roy Noji of PolarStar sent in a good number of photos of their upcoming HPA Gearbox replacement system. The photos below show the HPA system that you can install on existing M4 AEGs. The advantage of the HPA system is you can adjust the power depending on game requirements, no need to open the gun and replace the spring. The airsoft gun will be tethered to an external HPA tank, but then you can just have the hose run through your webbing to avoid entanglement.
They will be taking pre-orders by December 10, just in time for the Christmas season, so watch for news here, or check their website for announcements.

Roy Noji of PolarStar has given Thumpy the privilege to post more photos of their HPA Gearbox Conversion prototype for you to checkout. This easily makes your AEG into an HPA-ready airsoft gun which you can adjust power according to the game requirements. What's more, Thumpy says that they're also planning a gas blowback version, which should be a welcome thing to give more realism to your converted HPA airsoft gun. No further details on the last tidbit and this enables PolarStar to jump into the lead for an HPA M4 airsoft gun as other HPA kits are mainly for AK and M249 variants.
Latest update from Thumpy with his posting at his blog of the short demo of the PolarStar AEG to HPA conversion gearbox.
