This is a premium M134 Parts Kit, which includes an unfinished 80% housing. Most of the parts in this kit were manufactured Garwood Industries. The impossible to find factory Garwood GCU being the crown jewel of the kit… Motor was made by Skurka / 3,000 RPM… Bolts and Feeder Delinker made by General Electric. Barrels look brand new. This would make an incredibly nice Post sample for any of you SOTs out there.
