Enhance the quality of Picatinny setups with Arisaka's meticulously crafted 1913 Picatinny Rails engineered for seamless compatibility with the Arisaka Rail Slider. Each rail is equipped with an anti-rotation QD socket at one end and comes with both standard and short screws which are specifically designed to resolve clearance issues associated with gas blocks or thicker barrel contours. The length specifications are determined by the number of full M-Lok slots the rails encompass. For instance the current Knights Armament SR25 CC requires the 8 M-Lok slot rail to adequately cover the entire 6 o'clock position on the handguard.Crafted with precision these rails offer three M-Lok slots and are built from CNC machined 6061-T651 aluminum. They boast a MIL-A-8625 Type III hard coat anodized finish and are proudly manufactured in the USA. For optimal performance the recommended torque is 30 inch lbs for metal handguards and 15 inch lbs for polymer handguards. Ideal for handguard accessories this anodized rail is a perfect fit for M-LOK systems being part of the Rail Slider model collection.
