HMS HENNEBERGER STEYR swivel mounting - bridge swivel mounting | with PICATINNY rail

The technically sophisticated STEYR swivel mount was installed on countless STEYR bolt action rifles built in the 1970s to 1990s.
It was primarily installed on Steyr Mannlicher M models (Steyr SL, STEYR M, Steyr L, Steyr S), recognizable by the Makrolon plastic magazine with integrated feed screw.

The German scope mount manufacturer HMS Henneberger also offers newly manufactured upper parts for this original STEYR swivel mount, which is no longer available today, with which the weapon can be retrofitted with a contemporary optic.
This one-piece bridge swivel mount has a long Picatinny rail in accordance with the NATO STANAG standard.
This variant is particularly suitable for mounting modern night vision or thermal imaging scopes or various red dot sights with integrated Picatinny mount.

The position of the rear mounting clamp can be easily adjusted over almost the entire length of the bridge mount.
This ensures that the mount is compatible with all different STEYR system lengths.

Shot-proof, repeatable and can be swiveled up and down in seconds thanks to the quick-release fastener.

When choosing the right product, pay attention to the mounting base actually installed on your gun:
Unlike other swivel mounts (15mm prism with twist lock, EAW lever swivel mount), the original STEYR swivel mount has an absolutely square front base with the corner pointing towards the muzzle.
