Armaspec Arca Rail Features The Armaspec Arca Rail integrates directly with an M-LOK handguard giving an AR-15 or AR-10 a stable Arca-compatible mounting surface for bipods and other accessories that use the Arca-style standard. Constructed from 6061-T6 aluminum the rail keeps added weight to a minimum important for shooters who already carry a loaded rifle and want to avoid unnecessary bulk. At just 3 inches long and 0.08 lb it adds a mounting point without meaningfully changing the rifle s balance. The rail s stability allows for swift adjustments to bipods or other Arca accessories helping maintain control and accuracy during a shooting sequence. A Mil-Spec Type III hard coat anodized finish in Black protects the rail from the wear and corrosion that come with regular field use. This anodizing process is the same durability standard used across much of the AR accessory market so the Arca Rail is built to the same long-term expectations as the handguard it mounts to. Measuring 0.55 in height and 1.47 in width the rail keeps a low profile that avoids snagging on gear or clothing. For shooters building out a precision or competition setup around Arca-compatible bipods the Armaspec Arca Rail is a simple durable way to add that mounting standard to an existing M-LOK handguard.
