These fit directly onto the Blaser Saddle mount base that usually takes rings.
Tier One Picatinny rails are precision manufactured on 5 axis CNC machinery, going from round bar stock to the finished item in one operation. By doing this, there is no accuracy loss due to re-setting for different operations. All rails are made from 7075T6 Aluminium, and are available for various firearms. Tier One Picatinny Rails exceed the manufacturing criteria set out for the metric upgrade to the Picatinny Rail in 2009, STANAG 4694 NATO.
The rail overall length is 165mm. Mounting screws included.
Rails are available in 0-MOA or 20-MOA configurations. Blaser mounts on their own have 12 MOA elevation, so adding the 20moa version produces 32moa which is excellent for long range shooting.
Available for new style (R8) and old style (R93) saddle mount bases.
R8 Picatinny rails fit onto the new style saddle mount (saddle has large square slots that the rings fit down into):
