Bcd4
They go from full numbering blued to KM numbering phosphate SKM.
With an amazing array of cool stuff.
The best looking phosphate of the war.
Odd size laminate stocks
Machine gun barrel!
Heavily marked with all the subcontractor markings a, b, c, d, e, f, g, I, j, l, m, n, o,
Makes for an interesting rifle in my opinion.
