This part is discontinued and will never be made again.
Just so you can get going quickly, AGD includes a drop forward with the standard 3k Flatlines. For those of you (more like ALL of you) who want to upgrade, here is a must-have accessory. This dovetail adaptor will bolt right on to your Flatline's ring clamp and allow you to use most of today's popular drop forwards. The added advantage of the dovetail is that most drops allow you to remove the tank with one set screw. Clear anodized and designed with the Shocktech drop forward in mind.
