Magpul ACS-L in Flat Dark Earth FDE is a drop-in buttstock replacement for your AR-15 or M-16 rifle. The slim ACS-L provides the same storage compartment and sloping cheek weld as its predecessor but achieves lighter, slimmer styling by eliminating the battery tubes. Supplemental friction lock minimizes stock wobble for steady, accurate shots. Stock shape reduces snags and shields the release latch from accidental activation. Because, features include a durable chrome-silicone lock spring, replaceable 0.33” anti-slip rubber butt pad and reversible QD swivel sling mount that accepts 1.5” push-button swivels (not included). Additionally, compatible with Magpul ASAP® and other receiver-mount sling attachments.
