The Kinetic Research Group ARCA Rail Enclosed Forend is a competition focused version of the original Enclosed Forend for your KRG chassis. Includes an integral ARCA rail and M-Lok slots for your mounting needs. The top rail has been removed providing a comfortable grip for your offhand and just like the original it extends approximately 4" further than the standard forend offering plenty of real estate for bipod and other attachments.Since it's best to keep your scope as close to the boreline as possible, the ARCA Enclosed Forend has an area cut out over the barrel, which allows for the scope objective to sit low in a natural position. Fits: Whiskey-3, X-Ray, and Bravo Chassis
