The Area419 ARCALOCK Rail is a full-length Arca-Swiss dovetail built specifically for current production Barrett MRAD and MK22 rifles wearing the M-LOK forend. It gives precision shooters a single rigid platform for mounting bipods, tripods, and other Arca-compatible gear along the entire underside of the handguard. This rail is the right pick for anyone running an MRAD or MK22 in a positional or long-range setup who wants a dovetail that locks down hard rather than relying on clamp friction alone. Note that it does not fit older MRAD rifles built with the circular-hole forend, so confirm your forend type before ordering.
Area419 machines the rail from 6061-T6 aluminum and finishes it in Type 3 hard coat anodizing in Flat Dark Earth to match Barrett's factory coloring. It uses the company's 1.5-inch dovetail standard and attaches at up to four points along the M-LOK forend, running the full length of the MRAD/MK22 handguard for maximum mounting real estate. The serrated rail sides are what set the ARCALOCK system apart: they interface with Area419's proprietary clamp to mechanically lock an accessory in place so no movement is possible under recoil or load. The rail stays backward compatible with standard Arca clamps, though it will not lock without the matching ARCALOCK QD clamp. Radiused edges and chamfered corners keep it easy on hands and gear.
Shooters building out an MRAD or MK22 for matches, hunting, or duty work use this rail to anchor a tripod head for barricade and tank-trap stages, then transition to a bipod for prone without swapping hardware. Because it spans the whole forend, you get fore-aft adjustment for balance and recoil management on the gun. The rear barricade stop is sold separately if you want a hard reference point against props. Pair it with the matching clamp above, or browse our full selection of forend and handguard parts and the rest of the Area419 ARCALOCK lineup to complete the build.
No. The ARCALOCK rail is built for current production MRAD and MK22 rifles with the M-LOK forend. It is not compatible with older models that use the circular-hole forend, so verify your forend style before ordering.
It uses a 1.5-inch Arca-Swiss dovetail standard, so it mounts bipods, tripod heads, and other Arca-compatible accessories. Standard Arca clamps slide on and clamp normally; the serrated sides only mechanically lock when paired with the Area419 ARCALOCK clamp.
No. The rear fixed barricade stop is sold separately. If you want a hard reference point to brace against props and barricades, plan to add one to your order.
Area419 machines it from 6061-T6 aluminum and applies a Type 3 hard coat anodized finish in Flat Dark Earth. It is made in-house in the USA from USA-sourced aluminum, with radiused edges and chamfered corners for handling.
Not strictly. The rail is backward compatible with standard Arca clamps for normal clamping. To get the mechanical lock that eliminates movement under load, you need the matching Area419 ARCALOCK clamp that engages the serrated rail sides.
