This is the Spear LT chambered in 5.56. This is the all black model, not to be confused for the Rattler.
Normally the Spear comes in FDE or Multicam only however for LE/MIL versions they make them in Black they are just much harder to get.
Comes with the Sig Brace, Pmag 30 rd, and Romeo 5 Red dot to get you by.
