This is the 5 round factory rotary magazine in .308 for the Steyr SSG, which also fits the Steyr Model L.
Features the SSG logo on the base vs the huntimg scene of the Model L, otherwise the same.
The rotary magazine design is flush fit to the stock and is made of a tough polymer with a clear viewing plate at the rear.
Please note version is the 'squeeze to release' magazine type, early versions of the Model L with magazine releases on the trigger guard use a different magazine.
