CAA SBS Skeleton Buttstock for AR-15/M4

The SBS Skeleton Buttstock is a lightweight, nylon-reinforced polymer upgrade that snaps onto any Mil-Spec or commercial buffer tube without wobble, thanks to its extra-tight compression ring. A rubber-textured cheek weld and removable butt-pad add comfort and a non-slip shoulder pocket, while the ambidextrous, grooved release latch lets you make quick length adjustments, even with gloves or in low light. Three integrated sling mounts (web slot plus dual QD sockets) support multiple carry setups, and a thumb-activated pin-locking system keeps the stock locked solid for repeatable sight alignment. Overall dimensions: 7.48 in L × 1.77 in W × 4.92 in H.
