Designed as a drop-in unit to convert the gas operated G3 rifle to a blowback operated training rifle for low cost target practice, this kit consists of a recoil-driven bolt, a barrel sleeve, and a pair of weighted magazines. These components, along with a set of tools, are contained in a green painted hardwood case, marked "Einsteckgerat 5,6mm x 16/zum Gewehr G3" on the lid, with an inventory chart on the inside.

Excellent, showing a few light handling marks on the components and case.
