Product Overview

This Vltor SCAR Receiver Extension Stock Adapter is a drop-in, non-folding replacement part for the standard FN SCAR 16S or 17S factory buttstock assembly. The machined aluminum SCAR adapter provides a rigid platform onto which any mil-spec diameter collapsible AR-15 stock may be installed, resulting in an enormous amount of options from which the shooter may choose in order to personalize the rifle to his or her individual specifications. The Vltor SCAR stock adapter features 6 different length of pull positions and may also be adjusted up and down to alter comb height for use with different sighting arrangements. Unlike the OEM stock it replaces, the SCAR adapter incorporates a generous, o-ring sealed storage compartment inside the hollow extension tube with room to carry batteries, cleaning supplies and/or small spare parts. For shooters who don't use or feel the need for the side-folding capability of the factory supplied SCAR buttstock, the Vltor adapter is an excellent way to increase the gun's modularity by outfitting it with the ability to accept many of the different AR-15 collapsible stocks on the market. Comes complete with a pair of quick detach sling swivel sockets (one on each side of the adapter block).

Installation of the SCAR AR-15 stock adapter is simple, with no permanent alterations to the host rifle required. Remove the factory stock and slide the aluminum Vltor adapter block into the receiver, then slide the male dovetail of the receiver extension tube in from the top to engage the female dovetail of the adapter block. Adjust the extension tube up or down until the desired position is obtained, then use a bullet tip or other similar tool to tighten the large locking screw on the adapter's side to secure the tube to that location. A Mil-Spec diameter collapsible AR-15 stock may then be installed on the extension tube in the normal fashion.


This SCAR stock adapter is the Commercial variant, and fits Semi-Auto FN SCAR 16S (Light) and 17S (Heavy) rifles ONLY. Not compatible with select fire SCAR rifles.
