RSA Rail Sling Attachment for 20 mm Rails Black – FMA

FMA RSA (Rail Sling Attachment) in metal alloy, screwed onto any point of a 20 mm rail: it creates a low-profile attachment point for the hooks and snap clips of tactical slings, wherever it is needed on the replica.

Shape and style

The compact base wraps around the rail and carries a closed loop that barely protrudes from the replica's profile: a clean, minimal attachment that does not snag and leaves room for the other accessories on the handguard.

Mounting

It is positioned at the most convenient point on the 20 mm rail, on the handguard, receiver or stock, and locked in place by tightening the screw. It can be moved in seconds to set the sling up for right- or left-handed use or to find the right balance for the slung replica.

In the field

It is the simplest way to add a front or rear attachment point to replicas with rails, from M4 carbines to assault rifles and SMGs, for one- or two-point slings with clip-on hooks.
