If you bought the milled stock from Centerfire Systems and are looking for a trunnion you no longer have to look.
These trunnions are made like to the dimensions of a Romanian MD63 and work with the milled single locking stocks that are being sold on most websites. These will not work with a riveted together stock like the Polish, Yugoslavian or Hungarian stocks.
Made of 4130 then heat treated and black oxided. Order my MD63 Flat and convert standard 1mm kits into underfolder kits.
