Maximise the tactical and practical functionality of your GRS Bifrost rifle stock with this essential GRS Picatinny Rail 2 Pack. While the renowned GRS Bifrost stock comes equipped from the factory with a single accessory rail, discerning hunters and precision shooters often require additional mounting real estate. This convenient two-pack provides the perfect solution for attaching multiple accessories simultaneously, such as a bipod on the bottom and a high-lumen spotlight or IR illuminator on the side panels.

Engineered to match the rugged durability of the stocks they attach to, these rails are manufactured from a high-strength, 65% glass-fiber reinforced Polyurethane composite. This material ensures they remain incredibly lightweight (only 10 grams each) while providing a rock-solid, weather-proof mounting interface that will not warp or crack under heavy recoil or harsh field conditions.

Crucial Installation Note: Installation is designed to be permanent and incredibly strong. You will notice that the pre-drilled holes on your GRS Bifrost stock are not threaded. To install, simply locate and carefully remove the rubber plugs on the fore-end where you wish to mount the rail. Align the Picatinny rail with the holes, and using a slow-speed drill, drive the supplied screws in. The specialized screws are designed to self-thread, carving their way into the polymer stock. The friction creates heat, melting the stock material slightly into the threads for an exceptionally strong, permanent bond.

• Expand Your Options: The perfect upgrade for the GRS Bifrost, allowing you to securely mount multiple accessories like bipods, weapon lights, lasers, or barricade stops simultaneously.

• Ultra-Tough Composite: Constructed from a 65% glass-fiber reinforced Polyurethane/Polyamide blend, ensuring extreme durability and rigidity without adding unnecessary weight to the front of your rifle.

• Permanent Bond Installation: Utilizes specialized self-tapping screws that carve their own threads into the unthreaded stock holes, creating a fused, permanent bond that easily withstands heavy recoil.

• Universal Interface: Features the standard MIL-STD-1913 Picatinny profile, guaranteeing compatibility with a massive range of aftermarket shooting accessories.
