The Blaser R8 adapter provides a simple, secure way to fit a Spartan Magnaswitch™ support system to your rifle. It replaces the sling attachment point and fastens with the supplied M5 × 16 mm screw for a rock-solid mount. A longer M5×70 mm Allen-head screw is also included. Reattach your sling, clip on the bipod, and you’re ready to shoot.
