Area 419
The Area 419 Arcalock 8'' Universal Dovetail Rail brings mechanical locking precision to your precision rifle setup. Unlike traditional ARCA rails that rely on friction alone, the Arcalock uses serrated rail sides engineered to interface with Area 419's proprietary clamp design, creating a solid mechanical lock that eliminates movement under pressure—a real problem for shooters using barricade stops or shooting bags on standard rails. If you've watched your gear slide on a friction-fit ARCA system, you'll immediately appreciate the confidence this rail delivers.
Built to the RRS 1.5'' dovetail standard, the Arcalock maintains full compatibility with standard ARCA accessories while unlocking its full potential when paired with an Area 419 clamp. The 8-inch length spans your entire stock forend, giving you genuine flexibility for mounting bags, bipods, and supports exactly where you need them. At just 3 ounces, it adds virtually nothing to your rifle's weight—a critical consideration for hunters and long-range competitors who prize every tenth of a pound.
American-made from 6061-T6 aluminum on USA CNC equipment, the Arcalock is finished in Type 3 hard coat anodize for long-term durability in the field. Area 419 radiused every corner and chamfered every edge during machining, eliminating sharp points that can catch on bags, clothing, or skin—a small detail that reflects serious attention to actual use. The rail fits MPA CZ455 chassis without modification, and the serrated surfaces are deliberately non-aggressive so they won't damage your shooting support gear.
| Manufacturer | Area 419 |
| Product Name | Arcalock 8'' Universal Dovetail Rail |
| Rail Length | 8 inches |
| Weight | 3 ounces |
| Dovetail Standard | RRS 1.5'' |
| Material | 6061-T6 Aluminum |
| Finish | Type 3 Hard Coat Anodize |
| Manufacturing | USA-made on USA CNC equipment from USA-sourced aluminum |
| Known Compatibility | MPA CZ455 chassis (no modifications required) |
The rail is backwards compatible with standard ARCA accessories, but the mechanical lock only engages when used with an Area 419 clamp. Standard friction-based ARCA clamps will secure the rail but won't benefit from the locking serration design.
The Arcalock requires an Area 419 proprietary clamp to achieve the mechanical lock. MLOK hardware is not included with the rail.
No. Area 419 deliberately designed the serrations to be non-aggressive. The corners and edges are radiused and chamfered during machining to eliminate sharp points that could catch or damage gear or skin.
The rail is confirmed compatible with the MPA CZ455 chassis without any modifications required. As a universal dovetail rail built to the RRS 1.5'' standard, it should work with other platforms that accept that standard, but the CZ455 is the documented fit.
