GRS Bifrost

GRS Bifrost Green Adjustments

The Ultimate Adjustable rifle stock!

The main body of the Bifrost is made of glass fiber reinforced composite material. Rubber surfaces on the grip and fore end area assures full control during handling.  The SpeedLock 2.0 system has LOP and Cheekpiece adjustment, like the original speedlock system, but also includes a height adjustable and canting adjustable recoil pad.  This allows for the perfect stock to shooter fit. Additionally, the Speedlock 2.0 will withstand the recoil generated by the heaviest calibers. 

Picatinny Rail mounting points are located on the bottom and both sides of the fore end, and the bottom of buttstock. This makes for the easy use of lights, lasers, monopods, bipods and other devices.

Two picatinny rails are included with the stock, more are sold separately in sets of two.
