My brother just received his new Springfield Arms .308 Garand in the tanker (short barrel) version.
He called me up immediately and asked me to come over and look at the bore.
The gun has not been fired unless it was tested at the factory.
About 2" from the muzzle,it looked like a 3/16" long black face whisker was lying in the bottom of the bore. He had tried to remove it with patches,bore swab,and an all-brass brush to no avail.
When you raise your head slightly,you can see it has depth.It is about a land and 3/4's long and it has a slight pitch to it..Not having a good way to reference the width,I'd estimate it's at least 10 mils wide.
Not having a good borescope,it appears to be a deep tool mark or crack.
He called Springfield Arms and they asked him to return it to the factory.
Has anybody else heard of similar cases of Springfield Arms products.
I don't know if these barrels are swaged,broached,or ?
We had several swagers in our plant that we used to make "thimble tubes" which are used as guides for the control rods in a nuclear reactor.These tubes had final dimensional tolerances of +/- 0.0004 so it was a closely controlled process. I have seen interior defects like this and in most cases it was due to material defects or a dirty mandrel or lube.
