KAK Industry DBC Bolt Carrier Features The KAK Industry DBC bolt carrier is machined from 8620 steel to the M16 auto profile giving it the mass and geometry needed for reliable cycling in AR-15 rifles. The chrome lining inside the carrier resists the heat and friction generated by repeated firing helping the action cycle smoothly over a long service life. That same lining also simplifies cleaning since carbon and fouling have a harder time bonding to the polished chrome surface. Builders replacing a worn or damaged carrier get a drop-in part designed to the mil-spec auto profile. The exterior phosphate finish provides a parkerized layer of corrosion resistance that complements the internal chrome lining protecting the carrier from moisture and handling wear. Finished in black the KAK Industry DBC blends with standard AR-15 finishes for a factory-correct appearance inside the upper receiver. At 12.5 oz the carrier matches typical M16 profile weights keeping the rifle s cycling characteristics consistent with mil-spec builds. For shooters seeking a dependable correctly weighted bolt carrier for their AR-15 this KAK Industry DBC is a straightforward upgrade or replacement part.
