I got an incomplete PKT kit from century last week, it has all the main components for a gun, the bolt & carrier, trunnion, feed cover and pawl, back plate and sear housing. plus some misc other parts. best of all it was cheap!!
I am making a bbl out of a 1919 bbl, so far I have it chambered in 7.62 x 54R and fitted to the trunnion and shrunk on a sleeve for the gasblock. I still need to cut the locking lug. once the bbl is fitted I will make up a receiver from plate and set it up with a set of spade grips to make some sort of franken gun belt fed.
