This rail is attached to the front of Blaser R8 or R93 in the same manner as the R8 Spigot. Remove your sling attachment point and insert the rail, secure with an m5 screw. This updated version has a built in sling attachment point, and an optional in the front.
There are two versions of this rail:
– for original Blaser sling
– for Uncle mikes/ Grovtec sling
