The UTG Pro S1 is a full-size collapsible AR-15 stock built around a mil-spec carbine receiver extension, with a longer body and dual storage tubes for shooters who want more cheek and shoulder contact than a minimalist stock provides. Waterproof storage caps protect batteries and small accessories, while the reversible QD socket and traditional sling loop provide multiple sling attachment options. Black and Flat Dark Earth versions share the same design and specifications.
