VISM Sharp MILSPEC Stock Tan The Vism Sharp MILSPEC Stock is for MIL-SPEC buffer tubes. The tube is not included. It features a sleek design with metal QD base on each side for QD slings and several molded in 1.50 in sling loops. An integrated rubber butt pad is for non-slip secure shouldering, comfort, and recoil mitigation. The unique latch mechanism works by a first click for adjusting stock position and a second full click for mounting and demounting from the buffer tube
