Vltor M1A/M14 Modstock and CAS-14 rail
The M14/M1A Modstock (model M1S) from Vltor Weapons Systems is a drop-in replacement stock for the M1A. It offers adjustable length of pull and stock height, plus a pistol-grip configuration.
The M14 Modstock is a modified military/G.I. fiberglass stock, which Vltor modifies and refinishes in black, foliage green or FDE (Flat Dark Earth – shown here). Vltor cuts off the rear portion of the stock, and installs a machined aluminum adaptor. The adaptor comes standard with a TangoDown Battlegrip attached, but any AR-15 grip may be substituted. On each side of the adaptor are female QD sling cups, for attaching a QD sling swivel. A 1-1/4″ QD swivel is included. Vltor now puts a laser-engraved UID code and serial number below the swivel cup on the right side of the adaptor.
