About Toolcraft AR-10 / 308 / 6.5 Creedmoor Bolt Carrier Group w/ High Pressure Bolt - Ion Bond DLC - TC260-013

This Toolcraft 308 / AR-10 / 6.5 Creedmoor DLC BCG is trusted by weapons manufacturers and custom rifle builders around the world. Now you too can get this outstanding BCG at a fraction of the cost. The Diamond-Like Carbon Coating is a relatively new and highly desired coating for BCG’s. DLC has a very low coefficient of friction, is self-lubricating in dry conditions, extremely resistant to wear, highly resistant to corrosion, and one of the hardest coatings at 90 Rockwell. DLC is tough, so it features additional lubricity over Nickel Boron, and if you want a smooth running BCG that’s easy to clean, this is the one for you! The bolt is CNC machined from heavy duty 9310 alloy steel. 9310 steel has a high core & fatigue strength rating, a high hardenability rating, and when properly treated it is actually about 7% stronger than the “mil-spec” Carpenter 158 steel. The bolt is then shot peened (stress relieved) and finished with the same Ion Bond DLC as the carrier. The bolt also comes completely assembled with mil-spec gas rings, and a high tensile 4140 steel extractor. The bolt is also Magnetic Partical Inspected (MPI) for quality assurance. The DLC Carrier is machined from 8620 Toolcraft proprietary steel. The gas key is DLC finished 4130 steel, fastened to the carrier using Grade 8 screws and then properly staked. The carrier also features forward assist serrations. These Toolcraft Inc. BCGs come from the factory with a Lifetime Replacement Warranty. Plus, with the AR-15Discounts satisfaction guarantee, you can buy your AR build components without apprehension. Our guarantee says if you are unhappy for any reason, you can send it back to us within 30 days for a full refund. No worries.
