NOTE: Rail kits now come with only one action screw, and it is a longer screw. With the endless action/stock/chassis combos we found that nearly everyone was required to trim the screw for fitment anyway, so the longer screw makes much more sense. MLOK HARDWARE IS NOT INCLUDED.

Area 419 is always looking for ways to improve existing products when we are not developing new technologies. With the rapid growth in popularity of ARCA rails in precision rifle, we saw a need to improve this great dovetail technology to something that could be mechanically locked in place instead of just friction. If you have ever tried using a Barricade stop on an existing ARCA rail, you’ve probably also seen it slide under much pressure.

Introducing the ARCALOCK Dovetail Rail System *Rail is only locking with an Area 419 clamp*

Rail Features:

• Universal rail design is the same footprint as our previous rail. (There were two revisions to the hole spacing, if you have a very early model your hole spacing may change)
• 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.
• 65 Locking positions available on the 14″ rail
• Rail is backwards compatible with standard Arca accessories, but will not be locking without our clamp
• Serrated fixed rear barricade stop is same as before, but now we include an extension plug to raise it by another 1/2″
• 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 5.6oz
• 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.
• While designed with Manners Composite Stocks in mind, this rail accommodates a multitude of rifle and stock configurations that have an accessible front action screw and some sort of front attachment point(s).
• Spacers for rifle stocks with non-flat forends are available HERE
• Designed to attach to the rifle up to 4 places for maximum strength and stability.
• Extends past the end of most rifle stocks, allowing a further forward bipod attachment, increasing stability.
• 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 one Remington 700-style action screws of extended length to fit the rail to the front action screw attachment point. Some trimming will likely be required.
• A 3/4″ paddle bit and drill press may be required for installation of tee-nuts, depending on current rifle configuration. Tee nuts and hardware included.

Rail Weights:

• 14″: 156.03 Grams
• 12″: 111.5 Grams
• 10″: 95.2 Grams
• 8″: 82.5 Grams
