Toolcraft .223/5.56/300 BLK M16 Profile Bolt Carrier Group - Nickel Boron

Toolcraft .223/5.56/300 BLK M16 Profile Bolt Carrier Group - Nickel BoronThe Toolcraft 5.56x45 NATO/.223 Rem (or .300 Blackout) Bolt Carrier Group features a Nickel Boron finish to reduce overall wear and friction, and is ideal for upgrading your existing AR build. These Full Auto M16 Profile Direct Impingement BCG designs feature multiple characteristics that distinguish them from the average AR Bolt Carrier Group. They are Magnetic Particle Inspected for Quality Control and built to Mil-Spec standards throughout. They feature Mil-Spec 8740 steel, hard-chromed firing pins, Mil-Spec Gas Keys with Grade-8 screws that are staked and sealed with Permatex No. 3, and shot-peened, case-hardened D2 tool steel extractors. These Toolcraft Inc. BCGs come from the factory with a Lifetime Replacement Warranty on the entire BCG.Specifications Gas system: Direct Impingement Caliber: 5.56x45mm NATO/.223 Rem, .300 Blackout Finish: Nickel Boron Coating Bolt: 9310 Alloy Steel (High Hardness) Carrier: 8620 Aircraft Grade Steel Extractor: Shot Peened and Case Hardened D2 Tool Steel Firing Pin: Mil-spec 8740 steel with hard chrome finish Gas Key: Mil-Spec w/ properly staked Grade-8 screws and sealed with Permatex No. 3 Cam Pin: 8620 Steel w/ Black Nitride Finish Quality Control: MPI Inspected for QCNOTE- The Nickel Boron coating is well known for reducing friction because of its molecular structure. It offers excellent heat dissipation properties, reduces wear on the BCG and the corresponding parts, and increases the longevity of the BCG. Nickel Boron coatings are also known to reduce problems with function due to the decrease in overall friction and wear.Benefits Of Using A Nickel Boron AR-15 Bolt Carrier Group:A Nickel Boron AR-15 Bolt Carrier can provide several benefits to your firearm. The Nickel Boron coating is highly durable and corrosion-resistant, making it ideal for harsh environments and high-volume shooting applications. This durability reduces the need for frequent maintenance and replacement, ultimately increasing the lifespan of your firearm. The coating also provides a smoother surface than traditional steel, reducing friction and drag within the gun's moving parts, leading to more reliable cycling and less wear on internal components. Additionally, the self-lubricating properties of the Nickel Boron coating help retain lubrication, further reducing wear and increasing the firearm's lifespan. Overall, a Nickel Boron AR-15 Bolt Carrier can enhance your gun's reliability, durability, and longevity.
