Genuine Surefire light with manuals. Here are the parts:Model L60 Lamp module 6 V($99.00), Model XM00 dual switch tailcap assembly ($72.00), Model A21 adapter($30.00), Model SR07 rail mount tape switch ($80.00) and Model Z41 waterproof tailcap assembly ($42.00). The size of the light with the z41 tailcap is exactly like a Surefire 6P except that this is a true weapon light. It has over $350 in parts! The parts are brand new and never used. Its been sitting in my safe. I'm also including a free KZ 1' offset mount and a YHM spacer just in case you want/need more space to clear the rail. The KZ mount sits very close to the rail without the spacer. $200 shipped anywhere in the US. Priority mail with confirmation. Paypal.
