Thanks very much.

If I'm not mistaken, the ref I read was about an 03 with a JA barrel in it. I can't find it now of course.

The rifle looks like a dalliance between an M16 (look at the bolt and stock spring) and a Garand (upper receiver and magazine). Not unattractive in its own weird way.

I just didn't know if they were regularly involved in some aspect of the custom rifle trade along with their military operation.
