The Ultimate Bolt Carrier Group is machined from a solid piece of alloy steel, eliminating the need to stake the gas key and deleting the ability for gas key screws to come loose under operation. The carrier itself is NP3 coated and features a chrome plated bolt. This group features a stainless steel gas inlet tube that is pressed and pinned into the solid gas key. This tube has been designed to allow ample clearance for the removal of the roller cam pin during maintenance.
