Arisaka Low Profile Rail Features The Arisaka Defense Low Profile Rail is CNC machined from 6061-T651 aluminum and finished with a Type III hard coat anodized coating for long term durability. Its 5 slot design connects using three mounting nuts spreading the increased stress of larger Picatinny accessories like bipods or vertical grips across more attachment points on the handguard. This reduces the risk of damage to the handguard s mounting slots under heavy use. At only 2.15 inches long and 0.277 inches above the mounting surface Arisaka has removed roughly 40 percent of the height found in many competing rail adaptors. Keeping accessories closer to the handguard improves overall handling and reduces unnecessary bulk on a rifle build. The rail ships with mounting hardware making installation onto compatible M-LOK or KeyMod handguards straightforward. Weighing just 0.6 ounces this low profile rail adds minimal weight while still providing a secure Picatinny mounting surface. Arisaka Defense built this rail for shooters who want their accessories mounted as close and low profile as possible without sacrificing strength.
