GRS Piccatinny Rail 2 pc

Made from 65% glass fiber-reinforced Polyurethane, these rails are extremely durable.

They come in packs of two and are easily installed on your GRS Bifrost side panels on the fore-end.
Remove the rubber plugs from the Bifrost, line up the rail with the holes and use a slow drill to fasten.
The holes on the Bifrost are not threaded. The threads on the screw will carve their way into the stock and make a permanent bond. (material will melt into the threads)
