DPMS

FNC Treatment (Ferritic Nitrocarburizing) is a hardening process that improves barrel performance over Mil-Spec Chrome plating in terms of barrel longevity corrosion resistance and accuracy. By diffusing carbon and nitrogen into the barrel steel rather than adding a layer of material (as is the case in traditional chrome plating) the LCAR barrel is more durable and corrosion resistant without negatively effecting accuracy. - Caliber: 5.56 NATO - Weight (lbs): 6.4 lbs - Length: 36.5 - Barrel: 16 Lightweight FNC (Melonite) treated - Stock: 6 position Mil Spec M4 - Twist: 1x8
