Forward Accessory Mounting For Bolt Action Rifles
Stock Imbedded Rail Mount System (SIRS) lets you install night vision devices, optics, lasers and additional accessories up front, around the barrel and forearm, on a bolt action rifle. Features three MIL-STD 1913 Picatinny rails, including a 4" top rail that enables mounting of a night vision device in front of an optic. Compact side rails detach easily with an Allen wrench if not needed. Installation requires making a permanent cutout in the forend. Lower half is epoxied into cutout, then six, steel, Allen head screws clamp the top half on for a rock-solid installation that still allows the barrel to free float.
