Area 419 ARCALOCK 12″ M-LOK Dovetail Rail - FDE

The ARCALOCK Dovetail Rail System is designed to address the limitations of traditional ARCA rails by introducing a mechanically locking system. This innovation improves upon standard friction-based dovetail technology, ensuring a secure fit even under high pressure—such as when using a Barricade stop. It requires 6 consecutive MLOK slots for attachment, or a 12″ universal rail with MLOK attachment nuts for stocks with fewer slots. Compatible exclusively with Area 419 clamps, it is a robust solution for precision rifle enthusiasts.

Features:

• Serrated rail sides interface with our proprietary clamp design to mechanically lock it in place so no movement is possible. Serrations are not sharp, will not damage bags or your hands.
• Rail is backwards compatible with standard Arca accessories, but will not be locking without our clamp
• Rail is 12″ long giving you the entire length of the stock forend for attachments. The best part is, it still only weighs in at a paltry 4.1oz
• Made to the RRS 1.5″ Dovetail Standard, so you can be sure lever clamps will work
• No sharp edges. Every corner is radiused, and every edge is chamfered on the machine. This takes longer to make, but it is the only right way.
• Type 3 Hard Coat anodized for additional durability.
• Made from 6061-T6 Aluminum
• Made in-house here in the USA from USA sourced Aluminum on USA made CNCs
• M-LOK Slots on underside of rail also allow you to attach any M-LOK accessories to the 419 Rail
• Rail comes with all M-LOK mounting hardware
