Mil-spec bulk ammunition produced by PMC and imported from the Republic of Korea. The XP193 is a commercial reproduction of the original M193 55-grain ball ammunition used by the United States armed forces in their M16 and M4 rifles. PMC ammunition is popular for its consistency with lower variances in velocity and accuracy compared to other bulk mil-spec brands and makes for great general-use target ammunition. This product comes in a case of 500 rounds consisting of twenty-five 20-round boxes.
