The JCS Silver eTube is not intended for new users. It is designed for users with custom A5 or X7 marker setup. This tube has no FVA (front velocity adjuster) hole and no RT/Cyclone Feed Hole. It is constructed like the #75155 Red Hot Tube, but silver anodized. It is designed to be used on markers that do not utilize the FVA hole and bypass the RT/Cyclone Feed Hole. Marker owners that bypass the cyclone feed system use another feeding system like a Qloader. This item is also popular among non-cyclone feed A5 owners that utilize a low pressure set-up.

THIS ITEM SHOULD NOT BE USED WITHOUT A VELOCITY CONTROLLING DEVICE INSTALLED ON THE MARKER, SUCH AS JCS #66148 and a regulator. It should only be used if your marker setup utilizes a separate rear velocity adjuster or an RVA as part of a rear buttstock.

JCS does not recommend this item for new players.

Kit includes a JCS Hexadecagon Front Bolt - Updated 2009 version.
