Not to be confused with the Ultra-Compact Stock, the LWRC International Compact Stock is a drop-in replacement for AR15/M16 carbines with mil-spec diameter buffer tubes. It is a lightweight, no-nonsense stock that features integral sling attachment points, one-handed adjustment, and an excellent cheek-weld. The textured, rubberized butt-pad provides a positive non-slip interface with you or your gear.  Material: Glass-Filled Nylon 6/6 (body) Santoprene Elastomer (butt-pad)Weight: 7.9 oz.OAL: 6.357 in
