Overview

4 inch ARCA rail, 1.2 oz, with full-length mounting slots

The Salmon River SRS 4 inch ARCA is a compact rail that mounts to stocks or chassis with 10-32, 1/4-20 or M-LOK hardware, all included. It weighs 1.2 oz with a maximum hole spacing of 3.25 inches. The rail is made from 7075 aluminum with full-length slots that let you position the mounting holes to fit your build.

1.2 oz

Machined from 7075 aluminum, this 4 inch rail adds only 1.2 oz to the rifle.

Full-length mounting slots

Slots run the length of the rail so you can position the mounting holes anywhere within the 3.25 inch maximum hole spacing to match your stock or chassis.

Three fastener options included

Every rail ships with 10-32, 1/4-20 and M-LOK hardware, so one part covers stocks with 10-32 or 1/4-20 studs and M-LOK forends.

Two ways to mount

Bolt to existing 10-32 studs on a Bergara or other dual-studded stock, mount into M-LOK slots, or drill and install with the included tee nuts and 10-32 fasteners.
