** Rear angled barricade stop sold separately, available HERE **

** THIS RAIL REQUIRES 6 CONSECUTIVE MLOK SLOTS TO ATTACH. FOR STOCKS WITH FEWER MLOK SLOTS, YOU’LL WANT A 12″ UNIVERSAL RAIL WITH MLOK ATTACHMENT NUTS **

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:
– 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.
– 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).
– 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

    robinette (verified owner) – June 16, 2019

    I put this Arcalock M-LOK rail on my Ruger Precision Rifle and it’s a perfect fit and match. I added an Area 419 fixed barricade block and Atlas bipod barricade Arca clamp on the rail. Everything fits and looks fantastic.

    Great machining. Snug fit in m-lok slots. And as described, the serrations for the arcalock are nicely chamfered and not sharp at all.

  18. Rated 5 out of 5

    GREGORY S. (verified owner) – April 15, 2021

    My main shooting discipline is 3 Gun. I moved into open class 2 years ago and a buddy recommended I move to Arca swiss interface for my rifle. I picked up an AREA 419 Arcalock rail and absolutely love it. Switching from bag to bipod or tripod is superfast. Disengaging and dropping an item on the move is 4x faster than dropping from a 1919-pic rail. With the locking feature, bipods don’t loosen or slide like on some other Arca swiss rails. I now have Arcalock rails on 5 different rifles.

    Richard (verified owner) – June 5, 2021

    I am very impressed with the precision machining and tolerances. This rail attached to M-Lok on my rifle precisely. All of the edges are chamfered which is important when holding the rifle by the rail. This adds functionality to a standard rail that 1913 rail can’t match.

    Rock solid. Mounts with four M-Lok screws. I’m very satisfied. I forgot to pick up a fixed barricade stop to go with it when I made my first purchase, amd had to order that desperately, after the first package was delivered. These guys ship fast, so I had it within three or four days.

    Excellent fit and finish, I will be adding another to my collection. The notches(saw tooth) was a brilliant idea as I can adjust the attachments exactly where I need them without having to crank on a nob excessively. well worth the money compared to a non grooved rail .

    I added the 12″ M-LOK Rail to my Bravo stock. This came out very nice. A little Dremel work to change the stock’s pivot stud hole to a M-Lok slot, and the fit was perfect. Note, I straddled the spacing between the stock’s slots with the rail’s alignment pads and screw holes. Not the original design intent, but it works great.
