4130 & 4140

G.T. · 01-10-2014, 11:40 AM

Looks like many of the major components are the equiv. of SAE 5115 steel?? I've never heard of it, much less used it?? But, it would seem to be an alloy steel with some hardening capability... How it compares to 4130 or 4140 is still not known to me.. Better, worse, interchangeable, I don't know?? Some parts like the frame and trigger are of low carbon grade steel which would be expected... All the info is readily available on the net... But, the list is just what I needed Thanks again Gerben!!!...

... best to all, til...lat'r....GT
