The tactical TriRail Scope Emerald 4X Series from Clearview Investments Inc. is precision crafted from a single billet of 6061 T-6 Aircraft Grade aluminum and designed with an integral, nondetachable "mounting deck" that eliminates the need for rings. The TriRails provide a compact platform to mount laser/light accessories for fast target acquisition. The versatile tactical scope accepts Weaver/Picatinny accessories. The nitrogen-filled one-piece tube guarantees a tight seal to prevent fogging. Its "camera-quality" lenses are Emerald multicoated to gather more light for increased visibility and reduced glare for low-light conditions. The 4X magnification and duplex crosshair provide a 22-foot field of view at 100 yards. The finish is anodized matte black. Suggested retail price is $129.99.
