Nickel Boron coatings play a pivotal role in enhancing firearm performance and durability. These advanced coatings are applied to various firearm components, including bolt carrier groups and upper receivers. Nickel Boron offers exceptional lubricity, corrosion resistance, and ease of maintenance. In the AR-15 and AR-10 platforms, these coatings reduce friction, ensuring smoother cycling and improved reliability, especially in adverse conditions.
