These Gen-X inine regulators came stock on all of the Gen-X line of ANS autocockers until 2005. These were also sold separatly as an aftermarket accessory. The first run of these came with a full sized gauge, this picture is of a later version when they went to the ANS mini gauges.
The early versions also say phase II on the side.

nice regulators in their day, but much lighter and improved inline regulators soon pushed these classics to the side.
