Guntec USA AR-15 M.C.S. Multi Caliber Collapsible Stock - Black

The Guntec USA AR-15 M.C.S. (Multi Caliber Collapsible Stock) is a rugged, drop-in buttstock designed for AR-platform rifles chambered in 5.56 NATO, 9mm, and .308 Winchester. Built around a high-density polymer body, the stock combines aluminum reinforcing with steel hardware for a tough yet lightweight package. An integrated QD swivel socket accepts a quick-detach sling mount, and the unit slides directly onto a standard mil-spec carbine buffer tube with no extra hardware required.

Finished in a non-reflective black anodized matte coat, the M.C.S. blends with most builds and holds up to hard handling without flashing under optics. The collapsible design lets the shooter adjust length of pull to fit their shooting position, whether running an AR-15 patrol carbine, an AR-9 pistol-caliber carbine, or an AR-10 .308 battle rifle.
