5.56 62GR Federal Lake City - Enhanced MK318 Mod 1 SOST OTM "Silver Bullet" Non-Lead (T556TNB1NL) was designed for the USMC, as a supplemental round to the M855 green tip, after an issue was identified with the M855 round.

The MK318 utilizes a 62 grain, open tip boat-tail match reverse copper bullet with a non-lead, nickel jacket "Silver Bullet". Where other rounds simply bounce off, this SBR round is barrier defeating, with superior penetration and better ballistic stability.
