The WMD Guns NiB-X Bolt Carrier Group without Hammer (brand part no. NIBXBCG-0001) is coated in WMD’s proprietary NiB-X finish and polished to reduce fouling adherence, so carbon build-up wipes away instead of baking on. WMD Guns backs the coating with a lifetime guarantee against chipping, spalling, or flaking, and it held up through more than 30,000 rounds of government protocol endurance testing without the coating wearing off. That durability is especially valuable in short-barrel setups and suppressed platforms, where extra heat and back-pressure punish a standard phosphate-finished BCG. This version ships without the hammer, for builders sourcing that component separately.
