ステアーAUG
A limited edition STG-556, a clone of the Steyr AUG A3, had a production run of only 1,000 rifles. There was a limited production of 232 rifles produced with an 18.5" heavy barrel after tests proved that length provided optimum accuracy over the 24" length due to barrel harmonics. Another limited edition Steyr AUG A3 clone, the STG-556 Gebirgsjäger, had a production run of 500.
