I have read in two books (one by Skennertonicon) that the indian 2a1(7.62) receivers were made from EN36A steel !!!!!! not trying to say Peter is wrong in anyway(but have we all been misinformed ??) anyway I have machined up lots of parts for machinery using this steel and had it casehardened, (i used to work for 23 years in one of the largest automotive plants in the southern hemisphere as a toolmaker) and found this steel was also used the in the Australianicon automatic arms SAR which went into the rifle trials against the styer aug F88 the manufacturer used en36A steel case hardened to a depth of 0.010" at 56 to 59 rockwel hardness (how do I know what they used? well I rang the guy who made the AAA rifles)

please feel free to comment as I would like to see these books proved wrong, and if so ill be selling my 2A1
