The Steyr SSG is not a military spec rifle.

Here in UK an M14 is a long distant memory, as we have not been allowed to have the real thing since 1988.

All firearms made in Europe conform to the CIP chamber dimensions, not SAAMI - Steyr is an Austrian brand, and as such uses the CIP dimensions.

The AIAW is made in England, and does likewise.
