Area 419 4" Universal Arcalock Rail

$ 45.00

Brand: Area 419

Area 419 released their lightest, smallest ARCALOCK rail to date with this 4" version. Weighing in at just 1.5oz, this will fir forend hole spacing of 2″-3.5″, just like their extremely popular Integrated Bipod (Picatinny) Rail. The rail also comes with t-nuts and hardware to allow you to install the rail closer to the magwell for tripod use if desired.


These rails are made of 6061 billet aluminum and will be sold only in a black hardcoat anodized finish.

Utilizing the ARCALOCK Dovetail Rail System

Area 419 is always looking for ways to improve existing products, and has once again set the bar with the new Arcalock system. They saw the need to improve on the existing dovetail ARCA rails with 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.

 Comes with mounting hardware for conventional wood or fiberglass stocks.

*M-Lok hardware is also available Here.

**Barricade stop not included but is available Here.
