The LMT SOPMOD Gen1 stock in black is the original six-position collapsible buttstock developed by Lewis Machine & Tool under the U.S. SOCOM SOPMOD Block II contract. Known to operators simply as the "LMT SOPMOD" or "Crane stock," this is the stock carried on Mk18 CQBRs, M4A1 Block II uppers, and HK416s across Naval Special Warfare, 75th Ranger Regiment, and CAG loadouts from the mid-2000s forward.
Features include: dual storage compartments in the cheekweld for spare batteries or small kit, enhanced rubber buttpad for positive shoulder purchase in armor, ambidextrous QD sling swivel sockets, and a reinforced glass-filled polymer body that's survived over a decade of hard service. Fits any MIL-SPEC-diameter carbine receiver extension — not commercial-spec. Gen1 carries the original, authentic profile and markings; this is the clone-correct stock for any Block II or early-GWOT SOF build.
If you're running a Daniel Defense Mk18, Colt 933/935, or BCM recce build and the furniture has to be right, accept no substitutes. Order yours today.
