DESCRIPTION

The Area 419 ARCALOCK 14" Flat MPA BA Rail delivers a major upgrade to traditional ARCA dovetail systems by introducing a true mechanical locking interface rather than relying on friction alone. Built for demanding precision rifle shooters, the ARCALOCK system prevents accessory drift even under heavy pressure, ensuring absolute stability on barricades and positional shooting platforms. Featuring smooth, non-abrasive serrations designed to work seamlessly with the proprietary ARCALOCK clamp, this rail offers a secure, repeatable, and fully controlled interface. The low-profile flat design is ideal for MPA and similar chassis while remaining highly adaptable to a wide range of rifle configurations. Made in the USA from high-grade aluminium and engineered for both strength and versatility, this rail is an essential upgrade for shooters seeking enhanced reliability, precision, and confidence in every shot.

– 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 14″ 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
– 65 Engraved positions for the clamp to lock into
– Fits the MPA BA and BA Comp chassis at a minimum, may also fit the Hybrid but we cannot say 100% yet. **Will not fit Lite**
– Spigot supports front of rail, but rail will work even if you do not have the MPA spigot, you may just see a small amount of flex with bipod fully forward
– Access to recoil lug wedge is not obstructed
– 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
– Rail comes with all necessary hardware
