Hat: Custom Cast Part
The Rest: Marauders Task Force Parts

This custom was actually cobbled together from two previous customs of mine (plus a grey button-down shirt that I had in my parts bin).
The head, hat, weapon, and harness are from my previous V1 Recondo custom. I have since bought another custom head that looks MUCH more like Recondo, so the generic Marauders Trooper style head was no longer needed. As it happens, the new custom Recondo head does not fit the hat I have, so the hat it no longer needed as well.
The legs are actually just the legs from my Tiger Force Bazooka.
