Question on bolt and Barrel

[jah141]

Ok I was striping a M1 for a friend The barrel seems to be after market markings are ( Arlington ORD VA .30-06 ) . It looks to be a good mil repo I could not tell until I looked for the dates on it. Now here's the big question the bolt is W.R.A. but it has an extra spring installed in it. The spring is under the rear of the firing pin. The bolt looks to have had an hole miled in it so that the fireing pin is spring loaded back.

Thanks for any help Jeff

I believe that your bolt has been modified by fitting a spring in the rear to reduce the possibility of slam fires occuring.There are some m-1 smiths that do this.

The barrel markings you posted is an import stamping and has nothing to do with who made the barrel. The barrel could still be USGI. What other markings are on the barrel? Look at the top (what would be under the rear handguard) and on the right side (where the op rod would be).

The M1 is not mine I was cleaning it and looking it over for someone. But I didn't see any other markings on it. The markings on the barrel were right where the normal markings would be.

The spring loaded firing pins were a commercial modification for use in .308 / 7.62mm NATO chambering. There was a rash of 'slam fires' with commercial ammo with their more sensitive primers. The firing pin mod seemed to do the job!..
