ULTIMATE BOLT CARRIER GROUP
Upgrade your direct impingement AR’s with the ultimate bolt carrier group.
The Ultimate Bolt Carrier Group was developed to solve simple issues that plague the standard direct impingement bolt carrier group. Our 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 high phosphate nickel 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.
