Deal Details
Daniel Defense MK18 RIII URG Features The heart of the MK18 RIII URG is its cold hammer forged 10.3 barrel with a 1:7 twist rate designed for durability and optimal performance across a range of bullet weights. The carbine-length gas system ensures reliable cycling in short-barrel applications especially when running suppressed. The upgraded RIS III handguard features M-LOK slots in place of traditional quad rails offering modularity and weight reduction without sacrificing durability. Dani
