Engineered in Norway by GRS Riflestocks, the GRS Bifrost Bridge is a dedicated forend bridge accessory built to expand the mounting capability of any GRS Bifrost composite rifle stock. Precision-machined from rugged, lightweight anodized aluminum, it securely attaches to the Bifrost forend to provide a rigid over-the-barrel mounting platform for forward clip-on night vision/thermal optics or top-mounted bipod adapters. Complete with installation hardware, this bridge brings chassis-style modularity and improved recoil management to your GRS Bifrost rifle setup.
